It will not be out of place to consider the ancient tradition, teaching and faith of the catholic church, which was revealed by the Lord, proclaimed by the apostles and guarded by the fathers. For upon this faith the Church is built, and if anyone were to lapse from it, he would no longer be a Christian either in fact or in name.
We acknowledge the Trinity, holy and perfect, to consist of the Father, the Son and the Holy Spirit. In this Trinity there is no intrusion of any alien element or of anything from outside, nor is the Trinity a blend of creative and created being. It is a wholly creative and energizing reality, self-consistent and undivided in its active power, for the Father makes all things through the Word and in the Holy Spirit, and in this way the unity of the holy Trinity is preserved. Accordingly, in the Church, one God is preached, one God who is above all things and through all things and in all things. God is above all things as Father, for he is principle and source; he is through all things through the Word; and he is in all things in the Holy Spirit.
