2 Peter 2:1 But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.

“Mortality and Immortality are mutually exclusive characteristics. If Jesus is God, he couldn’t have really died, for God is immortal by nature. Likewise, if Jesus died, he couldn’t really be God, for God cannot die. Immortality is not a fluctuating quality! A being is either mortal or immortal. You can’t have it both ways with this. Either Christ died, and he was mortal during his time of ministry 2000 years ago, or he’s God and could have never died. Pick one alternative, as holding both is simply untenable. Traditional Christians typically respond to this point with the idea stated above in the introduction, that Jesus was fully human and fully God. But look at the next point.” – Christadelphians

Why Jesus Christ is God

Another trait among the cults is the misunderstanding of the nature of Jesus Christ, they cannot wrap their head around the fact that the Lord Jesus before coming into the inhabited world (oikoumenē) always existed as the Word (John1:1) and is God because He shares the same divine nature as God the Father and the Holy Spirit.

The greek word for the ‘inhabited’ world is oikoumenē, here’s a better definition from the greek.

oikoumenē
1. the inhabited earth
2. the universe, the world
οἰκουμένη oikouménē, oy-kou-men’-ay; feminine participle present passive of G3611 (as noun, by implication, of G1093); land, i.e. the (terrene part of the) globe; specially, the Roman empire:—earth, world.

Therefore because of the Lord Jesus not being created as cult members would say, they try to demote the divinity of Christ stating that He was just a “man”. The Bible proclaims differently as we are going to prove right now. The book of Hebrew opens with a dialogue which is taking place between the Father and the Son.

Hebrews 1:1-3 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds; Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high;

Here we read that God in many times and ways spoke in the past to the fathers (first generation of Israel) by the prophets, has in these last day have spoken to us by His Son (Jesus). And Jesus was appointed heir of all things by whom He created the worlds. It goes onto say “when he had by himself purged our sins”. That’s speaking of the crucifixion of Christ when He had shed His precious blood at the cross.

As we continue reading the following verses we’ll come across a statement from God the Father when speaking to the Son (Jesus Christ). God the Father calls the Son God when we simply look at the text there’s no denying this fact.

Hebrews 1:8-9 But unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom. Thou hast loved righteousness, and hated iniquity; therefore God, even thy God, hath anointed thee with the oil of gladness above thy fellows.

It’s as plain as day we see God the Father tell the Son “But unto the Son he saith, Thy throne, O God,”. If God the Father calls the Son God then why don’t Christadelphians call the Jesus Christ God? Because they’re a cult who masquerades as being Christian; the same is true of Jehovah Witnesses. All cults share this common trait they all deny Jesus Christ as God manifest in the flesh (1 Timothy 3:16).

Let’s keep reading in the same chapter of Hebrews and see what the rest of the text says.

Hebrews 1:10-12 And, Thou, Lord, in the beginning hast laid the foundation of the earth; and the heavens are the works of thine hands: They shall perish; but thou remainest; and they all shall wax old as doth a garment; And as a vesture shalt thou fold them up, and they shall be changed: but thou art the same, and thy years shall not fail.

After reading these verses we can see that it clearly speaks of Jesus Christ as the creator. Let’s keep reading in the same chapter of Hebrews because it goes onto say that the Lord Jesus created all things, He “laid the foundation of the earth; and the heavens are the works of thine hands”. This is speaking of the account of creation and it fits perfectly with other scriptures which also say Jesus Christ is the creator (John 1:3, Colossians 1:16).

Keep this in mind that these passages are saying the Lord Jesus created all things. The Christadelphian will disagree saying Jesus is not God. Well, let’s look at another verse because this verse in Hebrews is a direct quote from an Old Testament scripture and we don’t believe that God’s word will ever contradict. The scripture I would like to bring to your attention to is in the book of Pslams.

Pslams 102 is a prayer from David to God as he was troubled.

Psalm 102:1 [[A Prayer of the afflicted, when he is overwhelmed, and poureth out his complaint before the LORD.]] Hear my prayer, O LORD, and let my cry come unto thee.

It speaks of the LORD being the creator talking about the account of creation, I hope you’re still following along; if you read Psalm 102:25-27 and connect that with Hebrews 1:10-12 there’s no mistaking that God created all things but the writer to the Hebrews applies this to Jesus Christ as being the creator.

Psalm 102:25-27 Of old hast thou laid the foundation of the earth: and the heavens are the work of thy hands. They shall perish, but thou shalt endure: yea, all of them shall wax old like a garment; as a vesture shalt thou change them, and they shall be changed: But thou art the same, and thy years shall have no end.

This proves that Jesus Christ is God, He’s not the God the Father or God the Holy Spirit; but the 3 persons of the Godhead (Trinity) are all co-equal and make up the 1 God. I know this is hard for cult members to understand therefore they try to dismiss this, but how do you reconcile this? Either you’re willing to say this is a contradiction or you’re forced into believing that Jesus Christ is God Almighty as He said in Revelation.

Why Jesus Christ is man

Now let’s focus on the man Christ Jesus. This is the part all the cults will agree on that Jesus Christ was truly a man. He had to be in order that He would be a perfect sacrifice for us on the cross. That’s why He took on flesh (John 1:14, Philippians 2:8, Hebrews 2:16) He took on human nature. An angel cannot die in our place neither can any other created creature. God Himself had to come into His own creation to redeem us by His blood.

Philippians 2:5-8 Let this mind be in you, which was also in Christ Jesus: Who, being in the form of God, thought it not robbery to be equal with God: But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.

In the above verse, it’s clear how Christ Jesus came “in the form of God” in addition “thought it not robbery to be equal with God” it was not robbery to be equal with God because He is God. And what did Jesus Christ do? “took upon him the form of a servant”, this is why Jesus would say I came to do the Father’s will. It’s goes on to say “he humbled himself, and became obedient unto death, even the death of the cross”.

The same verse in the Greek says:
2:6 ὃς ἐν μορφῇ θεοῦ ὑπάρχων οὐχ ἁρπαγμὸν ἡγήσατο τὸ εἶναι ἴσα θεῷ
hos (Who) en (in) morphE (form) theou (of God)

The Greek is very powerful and precise and makes it abundantly clear that Jesus Christ is not a lower form of god as the Jehovah Witnesses or Christadelphians would say. They focus on the humanity of Christ while neglecting His deity as being truly God.

Another reason why Jesus was also truly man was He is our Kingly High Preist, only a man can be our mediator between God and man. The verse I would direct your attention to is in the book of 1 Timothy.

1 Timothy 2:5 For there is one God, and one mediator between God and men, the man Christ Jesus;

A priest in the Old Testament had to be a man one from the line of Aaron the priestly line but Jesus Christ who is our great High Priest came from the line of Judah, king David. He also was made our High Priest after the order of Melchizedek, the book of Hebrews addresses this all for us.

Hebrews 5:6-10 As he saith also in another place, Thou art a priest for ever after the order of Melchisedec. Who in the days of his flesh, when he had offered up prayers and supplications with strong crying and tears unto him that was able to save him from death, and was heard in that he feared; Though he were a Son, yet learned he obedience by the things which he suffered; And being made perfect, he became the author of eternal salvation unto all them that obey him; Called of God an high priest after the order of Melchisedec.

Hebrews 6:20 Whither the forerunner is for us entered, even Jesus, made an high priest for ever after the order of Melchisedec.

Hebrews 7:11, 17, 21 If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron? … For he testifieth, Thou art a priest for ever after the order of Melchisedec. … (For those priests were made without an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou art a priest for ever after the order of Melchisedec:)

Do you see the great significance in this? If Jesus Christ was not truly a man then we would be without a mediator and in big trouble before God. This is why God (Jesus Christ) was manifest in the flesh, to be a ransom for us. And only a man can give HIs life for men.

1 Timothy 2:5-6 For there is one God, and one mediator between God and men, the man Christ Jesus; Who gave himself a ransom for all, to be testified in due time.

Angels cannot die in our place, therefore Jesus Christ is not an angel sorry Christadelphians but Jesus Christ is not Michael the Archangel. The Lord Jesus is the Creator of all things. The Christadelphians say “you can’t have it both ways” that’s just the point you and I are not God. We cannot do what Jesus Christ did which is die for our sins and rise again from the dead 3 days later conquering death and hell. But God can do both God can whatever He wants to do and did.

All cults like the Christadelphians deny that Jesus Christ is God, but Jesus Christ Himself said He’s God and that’s why the Jews picked up stones to kill Him.

John 8:58-59 Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am. Then took they up stones to cast at him: but Jesus hid himself, and went out of the temple, going through the midst of them, and so passed by.

John 10:31-33 Then the Jews took up stones again to stone him. Jesus answered them, Many good works have I shewed you from my Father; for which of those works do ye stone me? The Jews answered him, saying, For a good work we stone thee not; but for blasphemy; and because that thou, being a man, makest thyself God.

The Jews knew exactly what Jesus Christ claimed, that He is the Son of God and is God. Therefore we conclude and see how the cults are in serious error and need salvation. Depending on which cult you’re referring to they either deny the resurrection in some way or will try to put you in bondage under the law like Seventh Day Adventist. One thing all the cults have in common is that they all deny the “Trinity” or Godhead.

If you’re a Christadelphian

If you’re a Christadelphian we tell you out of love to leave the Christadelphians they are dragging you to hell, you’ll be separated from God for all eternity. They believe that it is possible to lose one’s salvation. (What They Believe, p. 212) They deny the doctrine of the Trinity. (What They Believe, p. 84-87) They deny that Jesus is God in flesh. (Answers, p. 22) They deny that Jesus existed prior to his incarnation. (What They Believe, p. 85, 86) They deny the personhood and deity of the Holy Spirit. (What They Believe, p. 115) They deny the substitutionary atonement of Christ. (Answers, p. 25; What They Believe, p. 71).

These are all serious errors among many others they hold too. If you never read the Bible for yourself without Christadelphian glasses, I seriously recommend that you read it for yourself without Christadelphian teachings. And test all things by God’s word, you need to take this very seriously it’s your eternity at stake and where you will be spending it either in heaven or hell you choose.
