In our present time there are innumerable church denominations that have have developed since the time of the early churches.
However, we are to be very careful when we decide to have fellowship of worship in any chuech because the word of God says:
“Keep thy foot when thou goest to the house of God, and be more ready to hear, than to give the sacrifice of fools: for they consider not that they do evil” (Ecclesiastes 5:1).
“He that burneth incense, as if he blessed an idol. Yea, they have chosen their own ways, and their soul delighteth in their abominations” (Isaiah 66:3).
“The sacrifice of the wicked is an abomination to the LORD: but the prayer of the upright is his delight. The way of the wicked is an abomination unto the LORD: but he loveth him that followeth after righteousness” (Proverbs 15:8-9).
“For the time is come that judgment must begin at the house of God: and if it first begin at us, [WHAT SHALL THE END BE OF THEM THAT OBEY NOT THE GOSPEL OF GOD]? And if the righteous scarcely be saved, where shall the ungodly and the sinner appear?” (1 Peter 4:17-18).
Jesus, the only begotten Son of God is very clear when he comes, says: “Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven” (Matthew 7:21). “For many are called, but few are chosen” (Matthew 22:14).
