Whether it is lawful to abstain altogether from communion?

❌ Objection 1 : It seems to be lawful to abstain altogether from Communion. Because the Centurion is praised for saying (Mt. 8:8): "Lord, I am not worthy that Thou shouldst enter under my roof"; and he who deems that he ought to refrain entirely from Communion can be compared to the Centurion, as stated above (Article [10], ad 3). Therefore, since we do not read of Christ entering his house, it seems to be lawful for any individual to abstain from Communion his whole life long.

❌ Objection 2 : Further, it is lawful for anyone to refrain from what is not of necessity for salvation. But this sacrament is not of necessity for salvation, as was stated above (Question [73], Article [3]). Therefore it is permissible to abstain from Communion altogether.

❌ Objection 3 : Further, sinners are not bound to go to Communion: hence Pope Fabian (Third Council of Tours, Canon 1) after saying, "Let all communicate thrice each year," adds: "Except those who are hindered by grievous crimes." Consequently, if those who are not in the state of sin are bound to go to Communion, it seems that sinners are better off than good people, which is unfitting. Therefore, it seems lawful even for the godly to refrain from Communion.
