So? The Church does not forbid enjoyng sex within marriage when the chance of pregnancy is ordinarily nil. The Church does not forbid from exercising prudent judgement and even praise such effective judgement. What it does forbid is
(1) any gesture of disrespect or exclusion of God, especially in matter where God plays a pivotal role;
(2) any violation of the commandment to be fruitful over the course of marital life, -- that is, it forbids deliberate childnessness.
I could split the hairs again in your post to me. I am not going there anymore. I will just remain utterly confused on this one teaching of the Catholic Church.
As I said in my opening post, I think the spiritual difference between NFPer's and those practicing artificial birth control are very, very minute. The bottom line for me, they both are INTENT on preventing a pregnancy/bringing life into the world at a particular time in their lives. The method by which they accomplish this is, at least to me, simply splitting hairs.
