The Holy Mass is the source and summit of the Christian life. Here, we are fed with the Sacred Word of God in Holy Scripture, which guides us through our lives, and with the Sacred Body and Blood of our Lord, which feeds our souls and brings us into deeper union with God. The first time we receive Holy Communion may happen at the age of 7, after a child has made their First Confession. Like Confession, we need the Holy Mass regularly, even often, as it is a pillar for faith, grace, and hope in our lives. The Mass is the most important event in the whole world, because it makes Christ present in this special way!
This video gives a brief overview of the Holy Sacrament of the Mass and First Communion.
