Here is an excerpt from the “Catholic Religion” a manual of instruction for members of the anglican communion by Vernon Staley- 1893 (Courtesy of google books on line):
iii. The Eucharistic Feast, commonly called The Holy Communion.
Our Blessed Lord ordained the Sacrament of the Eucharist in order that we might be able on earth to plead His Sacrifice before the Face of God, even as He does in heaven. But beyond this, He had a further object in view, and one of supreme importance, viz., that He might feed our souls with His Body and Blood.
That we may thus be able to feed upon Him, He has given to His Church authority to consecrate, by the power of His Holy Spirit, bread and wine to become His Body and Blood. When we receive the bread and the wine thus consecrated, we verily and indeed receive His Sacred Flesh and Blood.
This is what is known as the doctrine of the Real Presence. The term Real Presence signifies the presence of a Reality. This Reality is the Body and Blood of Christ, present in the Sacrament under the form of bread and wine.1 Our Lord’s presence in the Eucharist is a spiritual presence. By a spiritual presence we do not mean something unreal or figurative, but a presence which is not natural or material. Angels are spiritual beings, but none the less real beings. A spiritual presence is a presence of a supernatural kind,—of a higher order than a merely natural presence. Our Blessed Lord is locally present in heaven, He is spiritually present in the Blessed Sacrament.
Holy Communion is thus the most blessed and the most solemn Thing upon earth.it affords the nearest approach to God of which the soul is capable here below. When we come to the Holy Communion we should always remember that we are approaching the Throne of God. The Divine Liturgy of St. James instructs the celebrant to say,—” Not as being worthy, but looking up to Thy Goodness, I address my voice unto Thee. O God be merciful to me a sinner: I have sinned against heaven and before Thee, and am not worthy to present myself before this Thy sacred and spiritual Table, whereon Thine only-begotten Son, and our Lord Jesus Christ, is mystically set forth as a sacrifice for me a sinner.”*1 We should never speak of receiving bread and wine in the Sacrament, but rather of receiving the Body and Blood of Christ which are hidden beneath the bread and wine. The reader may learn much more about the Holy Communion by reading our Lord’s own words about it, recorded in the sixth chapter of the Gospel according to St. John, beginning at the twenty-seventh verse.
