YOUCAT Question n. 219 - How often must a Catholic Christian participate in the celebration of the Eucharist?

(Youcat answer) A Catholic Christian is obliged to attend Holy Mass on all Sundays and holy days of obligation. Anyone who is really seeking Jesus’ friendship responds as often as possible to Jesus’ personal invitation to the feast.

A deepening through CCC

(CCC 1389) The Church obliges the faithful "to take part in the Divine Liturgy on Sundays and feast days" and, prepared by the sacrament of Reconciliation, to receive the Eucharist at least once a year, if possible during the Easter season (OE 15; CIC, can. 920). But the Church strongly encourages the faithful to receive the holy Eucharist on Sundays and feast days, or more often still, even daily. 

Reflecting and meditating 

(Youcat comment) Actually, for a genuine Christian, “Sunday duty” is just as inappropriate an expression as “kiss duty” would be for someone who was truly in love. No one can have a living relationship with Christ without going to the place where he is waiting for us. Therefore, from ancient times the celebration of Mass has been the “heart of Sunday” and the most important appointment in the week.

 (CCC Comment)  

(CCC 1417) The Church warmly recommends that the faithful receive Holy Communion each time they participate in the celebration of the Eucharist; she obliges them to do so at least once a year.    

(The next question is: What sort of preparation do I need in order to be able to receive Holy Eucharist?)
