Clement of Alexandria

But it is God that makes proclamation to us, and He must be believed. "For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. Wherefore the Scripture saith, Whosoever believeth on Him shah not be put to shame."

"With the heart man believeth unto righteousness, and with the mouth confession is made unto salvation. Wherefore the Scripture saith, Whosoever believeth on Him shall not be ashamed; that is, the word of faith which we preach: for if thou confess the word with thy mouth that Jesus is Lord, and believe in thy heart that God hath raised Him from the dead, thou shalt be saved." There is clearly described the perfect righteousness, fulfilled both in practice and contemplation.
