We believe that there is one God,
eternally existent in three persons:
Father, Son, and Holy Spirit.

Matthew 28:19 ; Matthew 28:19 ;

Therefore go and make disciples of all nations,
baptizing them in the name of the Father
and of the Son and of the Holy Spirit,

John 10:30 ; John 10:30 ;

I and the Father are one.

Ephesians 4:4-6; Ephesians 4:4-6 ;

There is one body and one Spirit,
just as you were called to one hope
when you were called;
one Lord, one faith, one baptism;
one God and Father of all,
who is over all and through all
and in all.

The Trinitarian formula arose during the late 2nd Century
more than a hundred years after the death of Jesus.
It was argued over within the church
for the next two hundred years.

Surely we can not be sure of the form of true divinity
Yet Trinitarian theory does create a litmus test
for inclusion within the Christian community,
and thus a vehicle for clerical power,
which the church dare not abandon,
even if it carries little reality.
