Sacerdotalis caelibatus

"Sacerdotalis caelibatus" is a big, fancy Latin phrase that means "priestly celibacy." A priest is a special kind of religious leader who helps people connect with God and live a good life. And celibacy means that the priest chooses not to get married or have babies.

So, "sacerdotalis caelibatus" is a rule or a law that says priests should be single and not have their own families. This is because they need to focus all of their attention on their job as priests and helping people be closer to God.

Some people might think it's hard for priests to not have a family or a wife, but they believe that being close to God and helping others is more important.

Not all religions or churches have this rule, but it's common among Catholic priests.
