Msgr. George Lemaitre was Belgian Catholic Priest, astronomer and professor of physics at the Catholic University of Leuven. He was the first to propose the Big Bang Theory.

Your ignorance of the Teilhard case is obvious. He was never excommunicated (lovely series of alternate facts you introduce :) ) He was censored because of his ideas on original sin, and not because of his scientific research. The fact is that his groundbreaking (and often mystical) ideas cannot account for the reality of evil in the world. But the positive aspect of his visionary thought far outweighs its shortcomings. For this he has been widely recognised, and praised for, including the last three popes.  

It is OK to be critical, but when ignorance gets mixed with hate ... well, it is a deadly mix.
