God

There is one and only one living and true God. He reveals Himself to us as Father, Son, and Holy Spirit — three distinct Persons with distinct personal attributes, but without division of nature, essence, or being. God is infinite in holiness and all other perfections.

Hear, Israel: Yahweh is our God; Yahweh is one.
— Deuteronomy 6:4 (WEB)

Note

Three sub-sections in the BFM article: God the Father, God the Son, God the Holy Spirit.
