If you do not believe in God, or you wonder if he is largely absent from human affairs; if you wonder if the Catholic Church's claims really hold water, consider these events.
Why should this battle even be happening?
Why on this ground--over claims the Catholic Church almost alone makes?
Had this been a battle over abortion or same-sex marriage, then it would not involve claims that are uniquely those of the Catholic Church.
I predict there will be many folks who will, in these events, realize God is validating the Catholic Church--with all her blemishes and wounds--as the visible Body of Christ on earth.
Fellow Catholics, if you have ever wondered about, or doubted, the claims of our Church--if you have wondered about the teaching on contraception, if God really cared about it--then consider this moment. Why would God put his Church on trial over this issue--if it did not matter to him?
Consider what I just wrote. God is choosing to allow his Church to enter into a terrible trial...over contraception. Do you think it possible that this matters quite a lot to God?
I believe that the contraceptive mentality that pervades the West is at the root of many of our modern problems and that is why it matters so much. Contraception encourages immorality; it tells women that sex can be divorced from it procreative function and just to get used to being used, and tells men that women are for pleasure first and commitment, maybe, if you test drive enough of them before you find one you particularly like. Is it any wonder that marriage, so necessary for the nurturing of children, is falling by the wayside?
So yes, contraception matters to God because how men treat women and women treat men is fundamentally changed by neutered sex.
