But faith is the gift of God’s mercy, so that those who have been made guilty by law may obtain forgiveness. Therefore faith brings joy. It is not possible to be saved by the law but we are saved by God’s grace through faith.

—Ambrosiaster, Commentary on Paul’s Epistles

This is why it is important to know your roots. This could have been written by a Protestant Reformer. Instead, it was written by a Church Father. When we lose sight of our roots, we risk being changed into something we are not. That is especially true for Christ’s one Holy, Catholic, and Apostolic Church.
