Therefore, if Jesus is truly present (body, blood, soul, & divinity) in the most Holy Eucharist, then we can gaze upon Jesus and worship Him in His physical presence. Therefore, we are blessed with the awesome opportunity to worship Jesus through Adoration of the Blessed Sacrament, or most Holy Eucharist. In Eucharistic Adoration, the Eucharistic Host (the Body of Jesus) is placed in a gold monstrance to be adored.
At the Last Supper, on the night he was betrayed, our Savior instituted the Eucharistic sacrifice of his Body and Blood. This he did in order to perpetuate the sacrifice of the cross throughout the ages until he should come again, and so to entrust to his beloved Spouse, the Church, a memorial of his death and resurrection: a sacrament of love, a sign of unity, a bond of charity, a Paschal banquet 'in which Christ is consumed, the mind is filled with grace, and a pledge of future glory is given to us.
