>>256Sola Scriptura- Scripture Alone
The Bible alone and only the Bible is the source of all Christian truth. The link I provided explains why this is untenable, even from a biblical perspective.
Sola Fide- Faith Alone
Faith in Christ is the only ingredient of salvation, living righteously in your actions is inconsequential as long as you have faith. The Catholic Church teaches that mortal sin can still separate us from God after our baptism, and we must live righteously and do penance in order to merit a hope of salvation even after we have proclaimed and confirmed our faith.
