So, according to Church teaching, it is not inherently a sin to practice what is called "natural family planning," as the Magisterium allows it. However, it all depends on the intention behind its use. If it is done with an egoistic intention or a contraceptive mentality, meaning a deliberate avoidance of children or a lack of generosity, it could become sinful. Determining whether it is a sin in a specific case can be difficult, as Saint John Paul II explained. If done with a contraceptive mindset, it may lead to imperfections or, in some cases, even a venial sin. This must be examined carefully in each situation.
Couples must honestly evaluate their own conscience before God. I recall a thought from a wise priest, who was my professor of moral theology when I was a seminarian. He shared a profound insight: he said that when married couples stand before God on Judgment Day, God may show them the children they chose not to have. These children, he said, could have been citizens of heaven for all eternity. However, because of the couple’s lack of generosity, their egoism, and their failure to embrace a spirit of sacrifice, they avoided bringing these children into the world. God, in His desire to give life to those children, could not do so because of their misuse of natural family planning, just as much as sinful contraception.
I remember these words from my professor clearly, and I think it’s important to share them here. Married couples should reflect on this: when we face the judgment of God, could it be that we will see the children who could have been born to us, but were not, because we chose to avoid their birth?
