I think you happen to find yourself living right next to something that’s noteworthy but uncommon and not indicative of a major reason that 1 in 10 Americans are former Catholics. There is no single major reason, though- reasons for leaving or changing faiths are as diverse as America’s religious landscape, but there are certain things you can expect to
not see very much of.
I lucked out a little bit and found an interactive graph that gives the major reasons for why Catholics become Protestants. Here’s what it looks like.
71% say their spiritual needs were not being met.
70% say they found a religion they like more.
54% say they just drifted away.
50% say they stopped believing Church teaching in some way.
43% say they’re unhappy with the Church’s teaching about the Bible.
32% say they wanted a different atmosphere in a church service.
29% married someone of a different faith.
27% were dissatisfied with clergy in their former congregation.
23% are upset with teachings on homosexuality.
21% cite the clergy sex abuse scandals.
21% are unhappy with rules about priests getting married.
20% were uncomfortable with the feeling of community at congregation.
16% are unhappy with Church teaching on birth control.
16% didn’t like the way the CC treats women.
14% moved to a new community.
11% were unhappy with teachings on war/death/poverty.
11% said religion drifted too far from traditional practices.
8% said someone they were close to passed away.
3% said they became separated or divorced.
Based on the responses of Catholics-turned-Protestant, it looks like this reason is cited less often than all the other ones.
The total population of the US is bit above 300,000,000. Around 24% of America is Catholic, but the number of people initially raised Catholic is probably slightly higher than that. (It’s been going down with each generation, in spite of a disproportionately high number of Catholic immigrants). About 15% of Americans raised Catholic are now Protestant, while about 14% are unaffiliated- together, this comprises about 10% of the total US population. (You can imagine how much Catholicism would have fallen in America without the infusion of immigrants, especially when Catholic evangelism brings in less than a 5% increase from all other faith groups). From the first group of former Catholics (which comprises about 5% of the total US population), only 3% of these people say they left the CC because they became separated or divorced.
Take about 5% of 300 million and multiply by 3%…Nationwide, I’d say America’s got less than a half-million people who left Catholicism for that reason. Probably around 450,000. Out of about 15 million American Protestants who were raised Catholic.
This is where you find the data.
pewforum.org/Interactive-Reasons-for-Joining-Reasons-for-Leaving.aspx You should already be under the tab that says “Reasons for Leaving Childhood Religion,” but you’ll need to look at the first box that says “Raised Catholic” and select the section that says “Now Protestant.” I believe it will initially give you the data for those who are “Now Unaffiliated.”
You might also find the “Reasons for Joining Current Religion” section of interest. I was most interested in the comparison between a person’s reasons for joining Protestantism as an ex-Catholic and reasons for joining a different form of Protestantism. For the second one, “Moved to a new community” is much higher on the list, which makes sense given the extreme mobility of Americans throughout life and the comparative unavailability of certain Protestant denominations throughout the country- unlike Catholic parishes, which are everywhere. Not as many of them, but they’re everywhere. What’s really of interest, though, is that 4% of Protestants-turned-differentkindof-Protestant cite marriage/divorce as a reason for joining their current faith group, while only 2% of Catholics-turned-Protestant cite that reason. I would have expected the opposite.
