Definition
Tritheism is a Christian heresy that posits the belief in three separate and distinct gods, rather than the Trinity (one God in three persons: Father, Son, and Holy Spirit). It essentially denies the unity of God, viewing the Father, Son, and Holy Spirit as three independent divine beings. Tritheism is considered a deviation from orthodox Christian doctrine. Imagine it as like believing in three separate suns, rather than understanding light is one, seen in a prism as a spectrum of colours.
