Calmly and assertively tell your pastor about what is happening in RCIA. There is a good chance that somebody else in the parish will be willing to take their place, and if not, it is better for there to be a shortage of catechists than to have somebody inflicting harm on others. Where violations of sexual morality and ultimately against the family is concerned, the most grievous victims are vulnerable children. When we insult the family, we insult the Trinity. We insult community. We insult brotherhood. We insult charity.
Don’t let it make you despair. Libertine theology is its own worst enemy. When people flip the moral universe upsidedown and start changing morality in order to conform to culture instead of changing culture in order to conform to morality, the institution dies because people rightly ask “Why bother?” What can such theology offer that secular institutions cannot offer? Libertine theology makes itself obsolete. Conformists churches no longer have the potency to sustain their membership, because there is increasingly no struggle. There is no discipline. There is no austere cry towards growth of spirit and character. It is mankind’s destiny to grow towards God in the same way a tree grows towards the sun. It is precisely in this struggle that one finds joy.
What does this mean for the Catholic Church? The Catholic Church can be wounded, but it is impossible for it to be destroyed. There has always been enemies on the inside. Even when the clergy of the Church was constituted of 12 men it was not without its wolf. Don’t be surprised when you see Christians do what is wrong. Just keep going. The Church might lose one field, but somewhere else in the world, it gains one. This is why I love reading about Church history, because when I read it, I see, “WOW. The world was so messed up.” When I read her history, I regain the confidence that, yep, Jesus has got this. In history, there is no man, no woman, no teacher, no professor, no priest, or even any Pope that can do anything to change that. We once had a Pope whose first words as Pope were reported to be “I am Pope! I am Pope!” If the Church can survive that, it can survive some uncharitable catechists. Peace.
