The EucharistEssentials

At what age should children start attending Mass regularly?

The Eucharist

The short answer

Young children are welcome at Mass, but the obligation to attend begins after age seven. Canon 1247 obliges the faithful to attend Sunday Mass, and canon 11 says merely ecclesiastical laws bind those who have completed seven years of age unless the law says otherwise.

The obligation

Canon 1247 obliges the faithful to participate in Mass on Sundays and holy days and to avoid work that hinders worship, the joy of the Lord's day, or rest.

When it begins

That canon gives no age, but canon 11 says merely ecclesiastical laws bind those baptized or received into the Catholic Church who have sufficient use of reason and, unless the law says otherwise, have completed seven years of age. So canon 1247 binds those who have completed seven years.

Younger children

Children under seven are not bound, though they are always welcome at Mass.
