关于基督的神性（ Sermons on the Deity of Christ）
Next he adds, “This Word was in the beginning with God.” He had not said these two words together. He had said, “This Word was in the beginning” and “He was with God.” Now he joins the two together. That is why we must so contemplate Jesus Christ that we do not estimate that He is not true God and of the same essence with the Father. He has, to be sure, been created with respect to His human nature, but we must go further to know Him as our eternal God, Who is in such a manner our God that He is the wisdom of His Father which has been with God from all time. That, then, is the summary of it. Now when we remember this exposition (as it is simply expressed) it will suffice to instruct us for our salvation. Surely it is all we need to know about it.
