I need to explain the sacraments to my non-christian friends. so I’m wondering whether anyone could teach me the shortest possible way of explaining it without confusing them.
Sacraments are visible signs of spiritual realities – instituted by Christ – which confer grace.
What this means
first is that Christ made physical matter and actions
sacred, “set apart”. At his baptism in the Jordan, he sanctified all water to be used in baptism. At the Last Supper, he sanctified simple bread and wine to be used in the consecration and offering of the Eucharist. (That’s the “visible signs” part.)
Second, there is a spiritual reality infused to the visible sign. The spiritual reality of being baptized in water while the Trinity is invoked over you is that you receive the grace of God, the remission of sin (original and actual) and its punishment, incorporation into the Body of Christ, and being made a new creation as a temple of the Holy Spirit. The spiritual reality of the Eucharist is the Body, Blood, Soul, and Divinity of Jesus Christ being present under the appearance of bread and wine.
Third, these are instituted by Christ. Christ is the creator of the sacraments, the sustainer of them, and the chief actor in them.
Fourth, they confer grace. They are not merely “symbols” (in the modern understanding of the word) of grace, they actually confer it. The
act of baptizing, of receiving Holy Communion, of having hands laid upon you, of being anointed with oil, etc.,
confers grace.
A sacrament is a mystery; at the beginning of Mass, the priest says “as we prepare to celebrate
these sacred mysteries” referring primarily to the Eucharist. A non-sacramental theology eschews matter and the physical world in favor of an exclusively spiritual world; on the other hand, the Incarnation – by which God assumed a body of flesh – is the origin of sacramentality.
I’m probably not being helpful… Suffice to say, because man is a being of spirit (his soul) and flesh (his body), God chose certain “staples” of our physical existence – bread, wine, oil, water, union between man and woman, laying on of hands – and uses them to speak to us in His language of grace, a language in which we are called to
participate/
