Geezer reaction: If only this was ~1945 - ~1965 America, I'd say to find a nice little Protestant church* and start attending. An enormous number of such churches were either founded to meet such needs, or grew enormously during the baby boom.
(Not to say that any such churches were perfect. 50% of 'em were below average! But if you lived in a good-sized town, you'd probably have at least a few to chose from.)
*Assumpion - Roman Catholics, Jews, etc. would mentally translate this to "Catholic church", "synagogue", etc.
