You say it is correct, and you are right, but that is the Trinity and not what you believe. What it is not, is one person playing three different roles or using three different titles.
Here is a fuller text of the Creed:
"Whosoever will be saved, before all things it is
necessary that he hold the
Catholic Faith. Which Faith except everyone do keep whole and undefiled, without
doubt he shall perish everlastingly. And the
Catholic Faith is this, that
we worship one God in Trinity and Trinity in Unity. Neither confounding the Persons, nor dividing the Substance. For there is one Person of the Father, another of the Son, and another of the Holy Ghost. But the Godhead of the Father, of the Son and of the Holy Ghost is all One, the Glory Equal, the Majesty Co-Eternal. Such as the Father is, such is the Son, and such is the Holy Ghost. The Father Uncreate, the Son Uncreate, and the Holy Ghost Uncreate. The Father Incomprehensible, the Son Incomprehensible, and the Holy Ghost Incomprehensible. The Father Eternal, the Son Eternal, and the Holy Ghost Eternal and yet they are not Three Eternals but One Eternal. As also there are not Three Uncreated, nor Three Incomprehensibles, but One Uncreated, and One Incomprehensible. So likewise the Father is Almighty, the Son Almighty, and the Holy Ghost Almighty. And yet they are not Three Almighties but One Almighty.
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 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."
