Trinity= God, Jesus & the Holy Spirit
The trinity means that there are three parts to God NOT that there are three Gods. Christianity is a monotheistic religion so they only believe in one God.
Another way to think of the trinity is as the three forms of water:
- God (liquid) --> Water
- Jesus (solid- human form) --> Ice
- Holy Spirit (gas) --> Steam
God who is Father- the transcendent creator
God who is Son- Jesus who is immanent and personal, who came to Earth and lived a human life
