The Eucharist is the source and summit of our faith, it is the true presence of Jesus. We celebrate this great mystery at every Mass. As we receive the Body and Blood of our Lord, Jesus Christ we enter communion and are made one with Him and His life is grown in us. We are mandated as Catholics to receive this great Sacrament at least once a week if not as often as possible as true spiritual food and drink. The Church makes the Eucharist and the Eucharist builds the Church.
