The Church did not sell indulgences. That was a Protestant lie which is still perpetuated.
Without some evidence to back up your statement you cannot be believed. There is a great deal of information about the church selling indulgences. The first known use of plenary indulgences was in 1095 when Pope Urban II remitted all penance of persons who participated in the crusades and who confessed their sins. Later, the indulgences were also offered to those who couldn't go on the Crusades but offered cash contributions to the effort instead.
Why would Pope Pius V abolish the sale of indulgences in 1567 if it had never happened?
You should do some research instead of just making false claims.
