This is how we can know true Christian doctrine versus false ones. All religions that claim to be a “sect of Christianity” that diminish Christ’s divinity by stating He was not one with God, or He is the devil’s (who is an angel) brother, or a mere prophet—all these religions are false, counterfeit versions of Christianity. They change, add to, or take away from the Scriptures, or profess to have received a “new revelation” given by an angel, which the apostle Paul addressed directly in His letter to the Galatians:
“I am astonished that you are so quickly deserting him who called you in the grace of Christ and are turning to a different gospel— not that there is another one, but there are some who trouble you and want to distort the gospel of Christ. But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed.” (Galatians 1:6-9)
This is the truth about Jesus Christ:
“Long ago God spoke to the fathers by the prophets at different times and in different ways. In these last days, He has spoken to us by His Son. God has appointed Him heir of all things and made the universe through Him. The Son is the radiance of God’s glory and the exact expression of His nature, sustaining all things by His powerful word. After making purification for sins, He sat down at the right hand of the Majesty on high. So He became higher in rank than the angels, just as the name He inherited is superior to theirs. For to which of the angels did He ever say, You are My Son; today I have become Your Father, or again, I will be His Father, and He will be My Son? When He again brings His firstborn into the world, He says, And all God’s angels must worship Him. And about the angels He says: He makes His angels winds, and His servants a fiery flame, but to the Son: Your throne, God, is forever and ever, and the scepter of Your kingdom is a scepter of justice. You have loved righteousness and hated lawlessness; this is why God, Your God, has anointed You with the oil of joy rather than Your companions. And: In the beginning, Lord, You established the earth, and the heavens are the works of Your hands; they will perish, but You remain. They will all wear out like clothing; You will roll them up like a cloak, and they will be changed like a robe. But You are the same, and Your years will never end. Now to which of the angels has He ever said: Sit at My right hand until I make Your enemies Your footstool?”(Hebrews 1:1-13)
That means Mormonism, Jehovah’s Witnesses, and Seventh Day Adventists all teach counterfeit gospels and if they do not repent and stick to the simple truth of God’s infallible word, they will die in their sins and be condemned to eternal separation from God.
You can’t mix up something like Christ’s divinity. Our salvation resides in the fact that Jesus is the Son of God, who is one with the Father, who because of His sinless perfection, sacrifice on the cross, and resurrection from the dead, we who trust in Him as Savior and Lord will inherit eternal life.
I pray if you are in one of these religions that God will open your eyes to the truth and you will believe Him and His holy word over the faulty word of man who have raped God’s beautiful, simple, life-giving and freeing truth, that because of His great love for us, He sent His only Begotten Son into the world to save the world from sin and eternal death.
If you are unsure, just pray. Ask Him to please open your eyes to the truth. Read the New Testament yourself, without a teacher telling you how you must interpret it. For the Apostle John wrote in 1 John 2:27:
“But the anointing that you received from him abides in you, and you have no need that anyone should teach you. But as his anointing teaches you about everything, and is true, and is no lie—just as it has taught you, abide in him.”
Trust the Holy Spirit to teach you and be set free from the chains of your religion that you may enter into a powerful, joyful, love-relationship with the Son who loves you and gave Himself for you.
Praying for you,
