Everyone is familiar with Luther’s heretical teaching known as salvation through faith alone. This means that the single act which is necessary for salvation is faith, which for him, and for protestants in general, means trust in God. For Catholics faith means the assent of the intellect, by means of a supernatural virtue infused by God, to the truths revealed by God and proposed as such by the teaching authority of the Roman Catholic Church. Therefore for Luther, and for those who follow him, sins do not count against you in the order of salvation. There is no need to mortify yourself. No need to do penance. Luther said: “Be a sinner and sin boldly, but believe and rejoice in Christ even more boldly…No sin will separate us from the Lamb, even though we commit fornication and murder a thousand times a day” [1]
