Commandments of the Catholic Church

The chief commandments of the Church are six:

    1. To hear Mass on Sundays and holydays of obligation;
    2. To fast and abstain on the days appointed.
    3. To confess at least once a year.
    4. To receive the Holy Eucharist during the Eastertime.
    5. To contribute to the support of the Church.
    6. Not to marry persons who are not Catholics, or who are related to us within the third degree of kindred, nor privately without witnesses, nor to solemnize marriage at forbidden times.
7. To learn the truths of the Faith. 
The Pope has more recently added a seventh.
