Why should the Catholic Church take a position on alcohol and drug use and what should that position be?

Do you mean alcohol abuse? I assume you also mean illegal drug use.

Yes

The only reference made to these things in the Catholic Catechism is with reference to the virtue of temperance which “disposes us to avoid every kind of excess: the abuse of food, alcohol, tobacco, or medicine.” (CCC, 2290)

The Catholic Church, like many religious institutions, takes positions on various social issues in order to provide moral guidance to its followers. When it comes to alcohol and drug use, the Church recognizes the potential for these substances to be abused and the negative effects they can have on individuals, families, and society as a whole. Therefore, it is important for the Church to address these issues and help its followers navigate the complexities that arise from substance use.

To determine the Church's position on alcohol and drug use, one can refer to the teachings of the Church, including the Catechism of the Catholic Church, papal encyclicals, and official statements from bishops and clergy. These sources provide guidance on moral principles and values that can be applied to various aspects of life, including substance use.

The Church promotes the principle of temperance, which encourages individuals to have moderation and self-control in their consumption of substances. This means that while it is not inherently sinful to consume alcohol or use drugs in moderation and within lawful boundaries, excessive and irresponsible use is discouraged. The Church recognizes that alcohol and drug abuse can lead to physical and psychological harm, addiction, damage to relationships, and can impair one's ability to fulfill their responsibilities and duties.

Moreover, the Catholic Church emphasizes the importance of caring for one's body, as it is considered the temple of the Holy Spirit. Therefore, the Church advises against using substances that can harm the body or impair one's rationality and decision-making capabilities.

Ultimately, the Church's position on alcohol and drug use is aimed at promoting the well-being and spiritual growth of individuals and society as a whole. It encourages responsible use and discourages excessive consumption or any use that harms oneself or others.
