Clement of Alexandria
Patristic
c. A.D. 150–215
“For, in fine, the agreement and harmony of the faith of both contribute to one end-salvation. We have in the apostle an unerring witness: "For I desire to see you, that I may impart unto you some spiritual gift, in order that ye may be strengthened; that is, that I may be comforted in you, by the mutual faith of you and me." And further on again he adds, "The righteousness of God is revealed from faith to faith." The apostle, then, manifestly announces a twofold faith, or rather one which admits of growth and perfection; for the common faith lies beneath as a foundation.”
