Here is the personal testimony and declaration of faith of the apostle and missionary to the Goths during the time of the controversies between Arius and the church, and before the formulas that became standard requirements for membership of the orthodoxy. This man is as close to biblical revelation as I've read anywhere.
, Wulfila, Bishop and Confessor, have always believed thus and in this sole and true faith I make my journey to my Lord,
I believe
that there is only one God the Father, alone unbegotten and invisible, and in His only-begotten Son, our Lord and God, creator and maker of all things, not having any like unto Him. Therefore there is one God of all, who is also God of our God, And I believe in one Holy Spirit, an enlightening and sanctifying power. As Christ says after the resurrection to his Apostles: "Behold I send the promise of my Father upon you; but tarry ye in the city of Jerusalem until ye be clothed with power from on high." (Luke 24.49) And again: "And ye shall receive power coming upon you by the Holy Spirit." (Acts 1.8) Neither God nor Lord, but the faithful minister of Christ; not equal, but subject and obedient in all things to the Son. And I believe the Son to be subject and obedient in all things to God the Father
