The necessity of Holy Communion in our continuous struggle between sin and righteousness.
Until a man’s earthly life finishes its course, up to the very departure of the soul from the body, the struggle between sin and righteousness continues within him. However, high a spiritual and moral state one might achieve, a gradual or even headlong and deep fall into the abyss of sin is always possible. Therefore, communion of the holy Body and Blood of Christ, which strengthens our contact with Him and refreshes us with the living streams of the grace of the Holy Spirit flowing through the Body of the Church, is necessary for everyone.St. John of Shanghai and San Fransisco
