105) Call no man father
"And call no man your father upon the earth: for one is your Father, which is in heaven." Matthew 23: 9.
There is not only the spiritual sin of being called "Father" when Jesus said not to be. Ironically it is only now beginning to be exposed how huge numbers of children have been fathered by Catholic priests, who committed fornication and adultery behind the scenes. So ironic they love to be called Father. Many of these priests became the "godfathers" of these children.
Of course this statistic does not include the fornication and adultery committed by priests without pregnancy being involved. Father Gerry Nugent was shamed in 2007 when he admitted in a murder trial he had sex with student Angelika Kluk, a victim of serial killer Peter Tobin. As The Orthodox are less openly against contraception perhaps their fornication / adultery rate is about the same, but they left less women pregnant.
