Why do Catholics oppose artificial contraception?

Catholics oppose artificial contraception primarily due to the belief that it can lead to promiscuity, undermining the sanctity of marriage and sexuality. This perspective is rooted in the Catholic Church's teachings about the purpose of sexual intimacy, which emphasizes both the unitive aspect — the bonding of husband and wife — and the procreative purpose of marriage, which is to be open to the possibility of new life.

The concern is that the use of artificial contraception might encourage a more casual attitude towards sexual relationships, reducing the significance of the marital bond and potentially leading to behaviors that the Church views as contrary to its moral teachings. This belief reflects a broader standpoint within Catholic ethical teaching that prioritizes the dignity of human sexuality and the responsibilities that come with it.

Other options such as cost, health concerns, or effectiveness don’t encapsulate the moral and theological foundations of the Church's opposition to artificial contraception, as the Church’s primary concern lies in issues related to morality and the purpose of marital relationships rather than practical or health-related aspects.
