Clement of Rome:
"And we, too, being called by His will in Christ Jesus, are not justified by ourselves, nor by our own wisdom, or understanding, or godliness, or works which we have wrought in holiness of heart; but by that faith through which, from the beginning, Almighty God has justified all men; to whom be glory for ever and ever. Amen."
Clement of Rome was a Bishop of the church of Rome in the first century. Origen (born in the late 2d century) attests that he was the Clement mentioned in Philippians 4:3. The quote below is from Clement's epistle. Even as late as the 4th century Clement's epistle was actually read in many churches.
It is a wonderful confession of the evangelical faith though one should remember he is writing well before the controversies over justification in the Reformation period.
