St. John the Cassian the Roman (360 - 435)

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 would desire even more the medicine for our wounds. It is impossible to receive communion once a year, as certain people do ... considering the sanctification of the 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 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 dieses, rather than, blinded by pride, think that after one year we become worthy of receiving Them! - St John the Cassian the Roman (360 - 435)
