Non-Catholic websites hold no weight regarding Catholic teaching. Non-Catholics have been led astray by their denominations’ teachings on this subject.
The Catholic Church is infallible when teaching on faith and morals. She is the sure norm by which to form your conscience.
and why did the former pope’s team on researching birth control see it as not intrinsically evil between married people?
You have been misinformed. They did no such thing.
The “commission” was to study whether or not the birth control **pill **was a contraceptive, not whether “birth control” was intrinsically evil-- Church teaching already held that it was so.
The “pill” was brand new and so the Vatican undertook to study it, how it worked, etc, and apply the teaching of the Church to its use. This is no different from the Church studying the issue of stem cell research, cloning, or any other new medical technology as it becomes a reality.
They sought to understand how this “pill” worked, having had nothing like it before, and to determine if it contravened the moral law or not.
These people sent their findings to the Pope, he read them, and then he reiterated the constant teaching of the Church on contraception. The pill was deemed to be contraception.
and can you still be open to life and procreation but use birth control for a time?
No. The Church does not teach that one must be “open to life.” The Church doesn’t teach “openness to life” in some vague or general way.
if not then wouldn’t nfp be a sin because it is not open to life and procreation?
The Church doesn’t teach that one must be “open to life” in the way you are meaning it. What the Church actually teaches is that **EACH **act of marital intercourse
must be unitive and procreative-- objectively (that’s what it means when the Church says “ordered per se” to procreation). It must be an unaltered act of intercourse. One may not engage in intercourse and attempt to render it infertile.
NFP is information. One may use the information to decide whether or not to have intercourse (depending on whether one is trying to get pregnant or avoid pregnancy). But, if the couple engages in intercourse it is unaltered and complete-- it is unitive and procreative.
Contraception does not meet this moral criteria as one engages in the act of intercourse and simultaneously alters that act.
even though both ways you are still planning on having children in the future?
This is called proportionality and it was rejected by the Magesterium as a false understanding of the requirements of marital love.
Again, each act of intercourse must be both unitive and procreative, objectively. Not just “some” acts of intercourse throughout the marriage.
and could humane vitae be changed in the future (do you think)?
The Church’s teaching on contraception is part of the moral law. It cannot change.
