Is there only one God?

There is only one God.

Explanation

The belief in one God is at the heart of the Catholic faith. Although many ancient cultures believed in numerous gods, God revealed to Israel that He alone is the true God and that there is no other besides Him. Christianity continues this belief and teaches that there is one divine being who created and sustains all things. This truth does not contradict the doctrine of the Trinity. Catholics believe in one God who exists eternally as three divine Persons: Father, Son, and Holy Spirit. The three Persons are not three gods but one God. Belief in one God provides unity and meaning to all of reality because everything comes from the same Creator and is directed toward Him. Christians therefore worship God alone and reject every form of idolatry that places created things in the place that belongs to God.
