text: God is believed to be infinite and God 's presence may be perceived through the actions of Jesus Christ and the Holy Spirit .
simplified: Trinity is the teaching that God is three different beings ; the Father , the Son ( Jesus Christ ) , and the Holy Spirit . In the words of the Athanasian Creed , `` the Father is God , the Son is God , and the Holy Spirit is God , and yet there are not three Gods but one God . ''
