The issue of artificial contraception was brought up during Vatican II. Pope Paul VI formed a an advisory commission, which recommended that ABC should be permitted. The Pope disagreed and wrote Humanae Vitae, where ABC was condemned.
It is still a controversial issue because most Catholics use ABC, and many theologians, priests, etc. think it’s okay. The official stance of the Church is that ABC is a sin, but only a minority of Catholics are obedient to this particular teaching.
And that is an excellent example that demonstrates that truth is truth, not a ‘majority decision.’
Advisory Commissions are meant to advise, but they can get things ‘wrong’. Ultimately the Pope made a pastoral decision, and thank God he did. As the years go by it becomes more and more apparent just how right he was.
Truth is truth and remains truth, no matter how many would reject it.
Just as a false teaching remains false, no matter how many would embrace it.
Because teaching doesn’t depend on how many ‘accept it’ or ‘reject it’. Truth stands as truth, no matter what.
And the figure of those who supposedly ‘reject’ the teaching is, like all statistics, ‘manipulative’. Suppose you have a young Catholic who roughly between the ages of 21 and 26 becomes deluded by society (or even, heaven help us, by clergy who should know better)and practices ABC. And then suppose that by the grace of God the person becomes aware (through other priests who correct the mistaken one), or through forums which link to the actual teachings, etc. . . .and STOPS engaging in ABC.
Now for 5 years the person ‘went against Church teaching’, but often with either no knowledge that it was against, or with the mistaken idea that ‘conscience’ could supersede the teaching, or even flat out, ‘yeah, that’s what the Church says but I’m doing it MY way’. . .but then, hosannah, the lost sheep returned. And for the remainder of that person’s life, they abide by the teachings.
There are probably a lot of people out there who have been confused or deluded, willingly or not. And there are probably a lot of people out there who have come to their senses already, or will relatively soon. …
Of course, it doesn’t exactly HELP to have people continually try to keep preaching the same old dissent and acting as though "the people have spoken, it’s the CHURCH who needs to change’ and in essence trying to be millions of little popes of the church-of-one. Those who knowingly make life ‘more difficult’ in such a way will have to answer to God, and so we pray for them as well as for those who have been given false teachings and told to ignore the truth.
