The rhythm method is not considered immoral by the church. It involves a period of self-denial, refraining from sex for about a week to 10 days.
Aaahhhh.
However, "self-denial" is STILL denying the "God's will" to possibly produce another life.
I just think alot of this BC concern about *stopping* life *before* it even begins is absurd.
I also think it's tied to the old days when many children would die. The more you had, the more likely you were to "contribute" to the continuation of the society. If you only had 2, there was a good chance they'd be dead by age 10 and you'd have nothing.
