Early Church Evidence For Sola Fide

"The fourth-century writer Marius Victorinus (who converted to Christianity around 355), says of Paul's teaching in Galatians: "Therefore righteousness is not from the law; that is, justification and salvation come not from the law but from faith, as is promised."13 Commenting on the book of Ephesians, he says of God's grace, "He did not give back to us what was merited, since we did not receive this by merits but by the grace and goodness of God."14 Later he adds, "The fact that you Ephesians are saved is not something that comes from yourselves. It is the gift of God. It is not from your works, but it is God's grace and God's gift, not from anything you have deserved."15 And again, "Only faith [sola fides] in Christ is salvation for us."16
