St. Cyril of Alexandria considers what the Lord Jesus teaches us in John 6:56 – “He who eats my flesh and drinks my blood abides in me, and I in him.” He writes:
“Now if we really yearn for eternal life, if we long to have the provider of immortality within ourselves, let us not abstain from the Eucharist like some of the more negligent, nor let us provide the devil in the depths of his cunning with a trap and a snare for us in the form of a pernicious kind of reverence. “Yes, indeed,” someone might say, “But it is written, ‘Any one who eats of the bread and drinks of the cup unworthily, eats and drinks judgment upon himself’ [1 Cor 11:29]. I have examined myself and I see that I am not worthy.” But then when will you be worthy? . . . Make up your mind, then, to lead a more devout life in conformity with the law, and so partake of the Eucharist in the conviction that it dispels not only death but even the diseases that are in us [1 Cor 11:30].” (A Patristic Treasury: Early Church Wisdom for Today, Kindle Loc. 4998-5003)
Fr Vassilios Papavassiliou comments:
“As St. John Cassian put it, and which is a good note to end on, We must not avoid communion because we deem ourselves to be sinful. We must approach it more often for the healing of the soul and the purification of the spirit, but with such humility and faith that considering ourselves unworthy … we should more greatly desire the medicine of our wounds. Otherwise it is impossible to receive communion once a year, as certain people do … considering the sanctification of heavenly Mysteries as available only to saints. It is better to think that by giving us grace, the sacrament makes us pure and holy. Such people manifest more pride than humility … for when they receive, they think themselves as worthy. It is much better if, in humility of heart, knowing that we are never worthy of the Holy Mysteries we would receive them every Sunday for the healing of our diseases, rather than, blinded by pride, think that after one year we become worthy of receiving them.” (Journey to the Kingdom: An Insider’s Look at the Liturgy, Kindle Loc. 854-62)
