Book of Common Prayer (page 865)

So the Father is God, the Son is God, and the Holy Ghost is God.

And yet they are not three Gods, but one God.

So likewise the Father is Lord, the Son Lord, and the Holy Ghost Lord.

And yet not three Lords, but one Lord.

For like as we are compelled by the Christian verity to acknowledge
every Person by himself to be both God and Lord,

So are we forbidden by the Catholic Religion, to say, There be three
Gods, or three Lords.

The Father is made of none, neither created, nor begotten.

The Son is of the Father alone, not made, nor created, but begotten.

The Holy Ghost is of the Father and of the Son, neither made, nor
created, nor begotten, but proceeding.

So there is one Father, not three Fathers; one Son, not three Sons; one
Holy Ghost, not three Holy Ghosts.

And in this Trinity none is afore, or after other; none is greater, or
less than another;

But the whole three Persons are co-eternal together and co-equal.

So that in all things, as is aforesaid, the Unity in Trinity and the
Trinity in Unity is to be worshipped.

He therefore that will be saved must thus think of the Trinity.

Furthermore, it is necessary to everlasting salvation that he also
believe rightly the Incarnation of our Lord Jesus Christ.

For the right Faith is, that we believe and confess, that our Lord
Jesus Christ, the Son of God, is God and Man;

God, of the substance of the Father, begotten before the worlds; and
Man of the substance of his Mother, born in the world;

Perfect God and perfect Man, of a reasonable soul and human flesh
subsisting.

Equal to the Father, as touching his Godhead; and inferior to the
Father, as touching his manhood;

Who, although he be God and Man, yet he is not two, but one Christ;

One, not by conversion of the Godhead into flesh but by taking of the
Manhood into God;

One altogether; not by confusion of Substance, but by unity of Person.

For as the reasonable soul and flesh is one man, so God and Man is one
Christ;

Who suffered for our salvation, descended into hell, rose again the
third day from the dead.

He ascended into heaven, he sitteth at the right hand of the Father,
God Almighty, from whence he will come to judge the quick and the dead.

At whose coming all men will rise again with their bodies and shall
give account for their own works.

And they that have done good shall go into life everlasting; and they
that have done evil into everlasting fire.

This is the Catholic Faith, which except a man believe faithfully, he
cannot be saved.
