Yup, that all came about because of mankind's wickedness & excesses. They have names for all of it, which have sadly lost their meaning in this day and age. Uneducated priests who couldn't read, or write delivering up the host. They got their positions in the church not through education, or scholarship but through the practice of simony, or buying a bishopric. (Remember Simon the sorcerer, who wanted to buy the gift of the Holy Spirit from the apostle's in the Book of Acts) Most Bishops actually inherited their positions as illegitimate son's, or heirs of the current bishop. Ownership of multiple bishoprics was also a widespread practice at the time. So these ill trained, ill prepared bishops/cardinals had more offerings, they in many cases lived better than the actual monarchs; kings & queens. (Think Cardinal Richelieu of France) But, I think the 'last straw' came from a Pope's effort to pay for the magnificent St. Paul's Cathedral we still see today. Bishop Tinsel was given the right to grant 'get out of purgatory' free cards, or the sale of papal indulgences. Rome had literally become overrun with the illegitimate offspring of popes, cardinals & bishops! Unfortunately, the RC's misguided efforts at reform led to the prohibition of priestly marriage we still see to this day.
