Opposition to the Church

In the encyclical letter Humanae Vitae Pope Paul VI says:

It can be foreseen that this teaching will perhaps not be easily received by all. Too numerous are those voices - amplified by the modern means of propaganda - which are contrary to the voice of the Church. To tell the truth, the Church is not surprised to be made, like her divine founder, a "sign of contradiciton," yet she does not because of this cease to proclaim with humble firmness theentire moral law, both natural and evangelica. Of such laws the Church is not the author, nor consequently can she be their arbiter; she is only their depositary and the interpreter, whithout ever being able to declare to be licit that which is not so by reason of its intimate and unchangeable opposition to the true good of man.

Pope Paul VI is of course speaking about human sexuality and artificial birth control, but this caught my eye in context of the seemingly unending flood of rhetoric calling for the Church to change it's teachings on abortion, contraception, homosexuality, ordination of women, etc. I see so many of these people saying that they really do know and love thier Faith and that is why they are advocating change in order to make the Catholic Faith better. I wonder how many of them really do know the Faith? How many love the Faith enough to pick up the writings of the popes and and Church Fathers?

I think this will be a good quote to keep in mind when having "discussions" on various topics with some of my peers.
