Actually, until the year 1930 NO CHRISTIAN BODY or denomination accepted artificial or unnatural means of birth control. The Catholic view is based on the first “book” of revelation: The created universe – i.e., natural law (which is not the same thing as the law of the jungle).
The Catholic Church DOES allow birth control: It’s called Natural Family Planning, and it works
better than condoms and such (I won’t ask why, if your husband is Catholic, you don’t already know this

). A little manual by Christopher West entitled
Good News about Sex and Marriage" (get it through Amazon or Barnes & Noble) gives the Catholic position in Q&A format that is easy to handle. My constant chant,by the way, is that “NFP” does **not **stand for “Not For Protestants” – and in fact, many Protestants are beginning to reclaim the beauty of this theology of marriage and life – which has only been obscured in the last 75 years…
The fact that some Catholics fail to live up to Church teaching does not make the teaching incorrect.
As I said, there are “Catholic” ways of regulating the number of children you have, provided your reasons are serious. The papal Encylical
Humanae Vitae (vatican.va/holy_father/p…e-vitae_en.html,) in which Pope Paul VI re-stated the age-old teaching of the Church, includes economic, psychological, and social conditions among those “serious reasons.”
I’ll let somebody else tackle Purgatory; go to the CA home page and click on the tract there for starters.
