One of the biggest surprises when I finished active duty in the Army was the number of folks who, when I knew them and their families of origin some 25+ years ago were "active" Catholics, but who are now not involved in any way with the church. The few times we have talked about this it just seems that they see no value for them in "going to church" anymore. Their family lives are wholesome, they are active in various forms of helping others, and are doing quite well. All of them went to catholic schools at least through grade 12. They are fairly open in discussing these things.
