The Catholic Church stated many things years ago, that are not so today.  One can't sell indulgences.  But popes, bishops, and priests once did to raise money to build St. Peter's in Rome.  The Church used to teach that if a baby died without baptism, its soul went forever to Limbo.  There is no Limbo.  The official church ['official' means hierarchy] has taught things about human reproductive systems that it knows little about.  Most priests didn't receive much of an education in biology as seminarians, at all.  Few have degrees in genetics.  What they DON'T know about instances of same sex orientation in all species of animals is sad.  What they don't UNDERSTAND in same sex orientation in humans is frightful.    

Most of the people on this site [and others] condemning people with the same sexual orientation don't know any personally.  Most bishops don't know any as individual people, who are just as unique as hetrosexual individuals.
