A distinction without a difference.
The abuse of indulgences was endemic from the bottom to the top of the church structure. How is that NOT teaching?
Why is it so hard to say that they were wrong on selling indulgences without adding excuses?
The heresy of Indulgences has not ended. The Mariology mythos endemic in being rewarded for repetitions of the Rosary and wearing the Brown placards dedicated to the demigoddess Mary absolutions roars onward, always away from JESUS and toward the wide gate ... just more evidence that Catholicism is not Christianity in the same fashion that Islam is Christianity.
Words mean things.
The distinction defines the difference.
Here are the teachings that remained unchanged by the abuses:
Matt 6:14 For if you forgive others their trespasses, your heavenly Father will also forgive you; 15 but if you do not forgive others, neither will your Father forgive your trespasses.
Matt 7:21“Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father in heaven.”
Ephesians 2:8 For by grace you have been saved through faith, and this is not your own doing; it is the gift of God— 9 not the result of works, so that no one may boast. 10 For we are what he has made us, created in Christ Jesus for good works, which God prepared beforehand to be our way of life.
1 Corinthians 9:27 but I punish my body and enslave it, so that after proclaiming to others I myself should not be disqualified.
James 1:22 But be doers of the word, and not merely hearers who deceive themselves. 23 For if any are hearers of the word and not doers, they are like those who look at themselves in a mirror;
James 2:14 What good is it, my brothers and sisters, if you say you have faith but do not have works? Can faith save you? 15 If a brother or sister is naked and lacks daily food, 16 and one of you says to them, “Go in peace; keep warm and eat your fill,” and yet you do not supply their bodily needs, what is the good of that? 17 So faith by itself, if it has no works, is dead.
James 2:18 But someone will say, “You have faith and I have works.” Show me your faith apart from your works, and I by my works will show you my faith. 19 You believe that God is one; you do well. Even the demons believe—and shudder. 20 Do you want to be shown, you senseless person, that faith apart from works is barren? 21 Was not our ancestor Abraham justified by works when he offered his son Isaac on the altar? 22 You see that faith was active along with his works, and faith was brought to completion by the works. 23 Thus the scripture was fulfilled that says, “Abraham believed God, and it was reckoned to him as righteousness,” and he was called the friend of God.
James 2:24 You see that a person is justified by works and not by faith alone. 25 Likewise, was not Rahab the prostitute also justified by works when she welcomed the messengers and sent them out by another road? 26 For just as the body without the spirit is dead, so faith without works is also dead.
