Holy Communion, partaking of the Body and Blood of Christ, unites us with Him, increases our love of Him, obtains forgiveness for venial sin, remission of punishment incurred by sin, preservation from future sin, quieting of the violent passions of anger and lust; it acts as healing remedy of body and soul and pledges us a happy immortality. This medicinal effect of the Sacrament is a frequent theme in the post-communion prayer.
