St. John Cassian on Holy Communion
We must not remove ourselves from Communion of the Lord on the grounds that we recognize ourselves to be sinners. Rather, we should come to It more and more often, thirsting after the healing of the soul and cleansing of the spirit, but with such humility of soul and faith that. Considering ourselves unworthy of receiving such grace, we might yearn for greater treatment of our wounds. With the humility of heart with which we believe and confess that we can never worthily come into contact with the Holy Mysteries, we may receive them on every Sunday unto healing of our illnesses, lest, by exalting ourselves through a vain confident heart, we believe that after the lapse of a year we are worthy of receiving it.
