Luthers Church Postil, Third Christmas Day, 25,27,10
” In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things came into being through Him, and apart from Him nothing came into being that has come into being” John 1:1
“Thus the evangelist contends that both assertions are true: God is the Word, and The Word is with God; one nature of Divine essence and yet not one person only. Each person is God complete and entire, in the beginning and eternally. These are the passages upon which our faith is founded and to which we must hold fast. For it is entirely above reason that there should be three persons and each one perfect and true God, and yet not three gods but one God…
Believe me, as one who has experienced and tried it, and who does not talk into an empty barrel; the Scriptures were not given us for naught. If reason could have kept us on the right road, the Scriptures would not have been given us. Take an example of Arius and Sabellius. Had they clung to the Scriptures and disregarded their own reason, they would not have originated so much trouble in the Church. And our Scolastics might have been Christians had they ceased fooling with their subtleties and had clung to Scripture.
Therefore I have said that he who desires to proceed safely on firm ground, must have no regard for the many subtle and hair=splitting words and fancies (of the Arians), but must cling to the simple, powerful, and explicit words of Scripture and he will remain secure
