It is very true we often find Christians doing UnChristian Things. We also see surprising acts of long term self sacrifice and dedication. I’ve notice that most Christians like this do not publicize their work. They do not see their work as anything special
In many ways, the best Christians and the best scientists are equally bad at engaging the public. The best examples of both are not usually among the public representatives. It is best not to judge all of science or the Church by public Christians or public scientists.
I very much recommend reading about Gary Haugen, the founder of IJM.
