Nonsense. Telihard was never excommunicated. He remained a Jesuit priest in good standing, he continued to work in his filed as a scientist. Check your facts. 

What is a fact, is that despite his groundbreaking and visionary thoughts, his ideas have weaknesses. They simply cannot account for the reality of evil in everyday life. This remains a serious problem, but his visionary/mystical insights far outweigh these problems.  The last three popes repeatedly recognised and praised him.
