Why Eucharist at Least Once a Year?
Can someone go to hell if they don't partake of the Eucharist? I believe I read somewhere that we need to take it once a year at least. Why?
Catholics are obliged to receive the Eucharist at least once a year (Code of Canon Law, can 921 §1-2) to encourage the faithful to live a truly faithful life and benefit from the great sacramental graces of the Eucharist, since we are not supposed to receive Holy Communion in a state of mortal sin (Code of Canon Law, canon 916).
Regarding whether reception of the Eucharist is necessary for the salvation of souls, please see our previous answer on this subject.
