On Sunday we celebrated Corpus Christi. The reading for the feast (on the Thrusday) was from St Thomas Aquinas:

Since it was the will of God’s only-begotten Son that men should share in his divinity, he assumed our nature in order that by becoming man he might make men gods. Moreover, when he took our flesh he dedicated the whole of its substance to our salvation. He offered his body to God the Father on the altar of the cross as a sacrifice for our reconciliation. He shed his blood for our ransom and purification, so that we might be redeemed from our wretched state of bondage and cleansed from all sin. But to ensure that the memory of so great a gift would abide with us for ever, he left his body as food and his blood as drink for the faithful to consume in the form of bread and wine.

O precious and wonderful banquet, that brings us salvation and contains all sweetness! Could anything be of more intrinsic value? Under the old law it was the flesh of calves and goats that was offered, but here Christ himself, the true God, is set before us as our food. What could be more wonderful than this? No other sacrament has greater healing power; through it sins are purged away, virtues are increased, and the soul is enriched with an abundance of every spiritual gift. It is offered in the Church for the living and the dead, so that what was instituted for the salvation of all may be for the benefit of all. Yet, in the end, no one can fully express the sweetness of this sacrament, in which spiritual delight is tasted at its very source, and in which we renew the memory of that surpassing love for us which Christ revealed in his passion.

It was to impress the vastness of this love more firmly upon the hearts of the faithful that our Lord instituted this sacrament at the Last Supper. As he was on the point of leaving the world to go to the Father, after celebrating the Passover with his disciples, he left it as a perpetual memorial of his passion. It was the fulfilment of ancient figures and the greatest of all his miracles, while for those who were to experience the sorrow of his departure, it was destined to be a unique and abiding consolation.

Having written about the feelings that sometimes arise when engaging with Tradition, I must admit that I found some of the language somewhat challenging and yet at the same time I was helped by this passage in contemplating this mystery.

While reading on the Internet today I followed a link to one of the Vatican II documents, “Sacrosanctum Concilium”. Again, the language takes a little grappling with in one or two places. Dispite this there is so much that is worth reading here. These are two sections that struck me:

7. To accomplish so great a work, Christ is always present in His Church, especially in her liturgical celebrations. He is present in the sacrifice of the Mass, not only in the person of His minister, “the same now offering, through the ministry of priests, who formerly offered himself on the cross” [20], but especially under the Eucharistic species. …

Christ indeed always associates the Church with Himself in this great work wherein God is perfectly glorified and men are sanctified. The Church is His beloved Bride who calls to her Lord, and through Him offers worship to the Eternal Father.

Rightly, then, the liturgy is considered as an exercise of the priestly office of Jesus Christ. In the liturgy the sanctification of the man is signified by signs perceptible to the senses, and is effected in a way which corresponds with each of these signs; in the liturgy the whole public worship is performed by the Mystical Body of Jesus Christ, that is, by the Head and His members.

8.In the earthly liturgy we take part in a foretaste of that heavenly liturgy which is celebrated in the holy city of Jerusalem toward which we journey as pilgrims, where Christ is sitting at the right hand of God, a minister of the holies and of the true tabernacle [22]; we sing a hymn to the Lord’s glory with all the warriors of the heavenly army; venerating the memory of the saints, we hope for some part and fellowship with them; we eagerly await the Saviour, Our Lord Jesus Christ, until He, our life, shall appear and we too will appear with Him in glory [23].

In a slightly different tone, I loved this gentle meditation by Michelle from the Quantum Theology blog.

Writings of the Saints, Vatican documents and modern blogs; all shed light on the mystery of the Eucharist, where Christ is present in body and blood.
