I have read that the more often a Catholic attends Mass, the more likely said person attends, the more likely said person is politically conservative. I've also been told that only about 10% of Catholics attend Mass at least weekly. Putting the two together, they say that the number of "real Catholics" in this country is no higher than 7 million (i.e. not the 70 million or so that the USCCB reports).
But that's the maximum. If your 20-30% number holds true (and I believe it does), the number of (reliably) politically conservative, observant Catholics actually numbers around 5 million. This doesn't surprise me. It's one way to understand why Crisis Magazine would report this about The Mythical Catholic Vote: The Harmful Consequences of Political Assimilation:
Unfortunately enough, Catholics are largely indistinguishable from non-Catholics and, despite a few pundits, no, there really is no Catholic vote. This obvious conclusionclear enough from the fact that the vote for the winning candidates in the last national election was approximately the same for Catholics and non-Catholicshas serious current implications....
That quote is unfortunate in that it leaves out non-Catholic Christians, it would be great if Catholics voted like non-Catholic Christians.
"Putting the two together, they say that the number of "real Catholics" in this country is no higher than 7 million (i.e. not the 70 million or so that the USCCB reports)."
But for repenting at the end of life. One thing is for sure I know when someone is diagnosed with a terminal disease they do come back. I remember my neighbor reading the bible having any Catholic or Christian come in to talk and pray. So Thank God in a way for slow illness for them to get serious about there soul. I have done prayers myself to help make a real decision for Christ happen for many in terminal illness. Praise be to Jesus.
