The Doctrine of the trinity clearly states that God is three separate persons, co-eternal, co-equal. Many are taught that this theory must be accepted, that it is beyond human understanding, and must be accepted by faith. While I believe that there is much in the word of God that should be accepted by faith, I don't believe that a human theory that contradicts the word of God need be accepted at all.

In Isaiah Chapter 44-46 God clearly declares that there is no God beside him and no god equal to him, that he is alone. According to the trinity the three separate persons are having fellowship together during this period. Is 44: 6,8, 24 Is 45: 5, 6, 18, 21, 22 Is 46: 5, 9.

You need to stick with the Bible!

Isaiah 9:6 Clearly states that the child that is to be born is the everlasting Father, the Mighty God. In Matt 28:18 Jesus clearly states that he has ALL POWER, so if there were any separate "persons" they would be powerless.
Jesus even told Philip "He that hath seen me hath seen the Father." John 14:9

The doctrine of the trinity is simply carnal ungodly men attempting to explain spiritual things to other carnal men.

In Matt 28:19 Jesus told his disciples to baptise using a name. The apostles did use a name, they used the name of Jesus. Acts 2:38, 8:16, 19:5.

In Acts 9:5 When Saul cried out to God and asked God who he was, God answered and said, "I AM JESUS". The devil has many deceived into thinking that Jesus is a junior one third of god, when in fact JESUS IS THE MIGHTY GOD!
