“We acknowledge, indeed, that Christ in human nature is called a Son, not like believers by gratuitous adoption merely, but the true, natural, and, therefore, only Son, this being the mark which distinguishes him from all others. Those of us who are regenerated to a new life God honours with the name of sons; the name of true and only-begotten Son he bestows on Christ alone. But how is he an only Son in so great a multitude of brethren, except that he possesses by nature what we acquire by gift?” SonAdoptionTrinitySonshipBegottenArianismModalismServetus Book:Institutes of the Christian Religion, 2 Vols Source: Institutes of the Christian Religion, 2 Vols
