When you visit Canterbury Chapel for a service of Holy Communion (The Lord's Supper,) the table set before you is not ours but the Lord’s. All those who truly and earnestly repent of their sins, are in love and charity with their neighbors, and intend to lead a new life, following the commandments of God, and walking from this day forward in His holy ways are invited to come to the altar with faith to receive the holy Sacrament.
In short: If your heart and soul belong to Jesus, then you are not only welcome but encouraged to take Communion with us.
More about what we believe with regard to the Lord’s Supper may be found in the 1928 Book of Common Prayer on page 608:
XXVIII. Of the Lord’s Supper.
The Supper of the Lord is not only a sign of the love that Christians ought to have among themselves one to another; but rather it is a Sacrament of our Redemption by Christ’s death: insomuch that to such as rightly, worthily, and with faith, receive the same, the Bread which we break is a partaking of the Body of Christ; and likewise the Cup of Blessing is a partaking of the Blood of Christ.
Transubstantiation (or the change of the substance of Bread and Wine) in the Supper of the Lord, cannot be proved by Holy Writ; but is repugnant to the plain words of Scripture, overthrows the nature of a Sacrament, and has given occasion to many superstitions.
The Body of Christ is given, taken, and eaten, in the Supper, only after an heavenly and spiritual manner. And the mean whereby the Body of Christ is received and eaten in the Supper, is Faith.
The Sacrament of the Lord’s Supper was not by Christ’s ordinance reserved, carried about, lifted up, or worshiped.
XXIX. Of the Wicked, which eat not the Body of Christ in the use of the Lord's Supper.
The Wicked, and those who do not have a lively faith, although they do carnally and visibly press with their teeth (as Saint Augustine said) the Sacrament of the Body and Blood of Christ; yet in no way are they partakers of Christ: but rather, to their condemnation, do eat and drink the sign or Sacrament of so great a thing.
XXX. Of both Kinds.
The Cup of the Lord is not to be denied to the Lay-people: for both the parts of the Lord’s Sacrament, by Christ’s ordinance and commandment, ought to be ministered to all Christians alike.
And in the first of “The Exhortations” on page 85:
DEARLY beloved in the Lord, ye who mind to come to the holy Communion of the Body and Blood of our Saviour Christ, must consider how Saint Paul exhorteth all persons diligently to try and examine themselves, before they presume to eat of that Bread, and drink of that Cup. For as the benefit is great, if with a true penitent heart and lively faith we receive that holy Sacrament; so is the danger great, if we receive the same unworthily. Judge therefore yourselves, brethren, that ye be not judged of the Lord; repent you truly for your sins past; have a lively and stedfast faith in Christ our Saviour; amend your lives, and be in perfect charity with all men; so shall ye be meet partakers of those holy mysteries. And above all things ye must give most humble and hearty thanks to God, the Father, the Son, and the Holy Ghost, for the redemption of the world by the death and passion of our Saviour Christ, both God and man; who did humble himself, even to the death upon the Cross, for us, miserable sinners, who lay in darkness and the shadow of death; that he might make us the children of God, and exalt us to everlasting life. And to the end that we should always remember the exceeding great love of our Master, and only Saviour, Jesus Christ, thus dying for us, and the innumerable benefits which by his precious blood-shedding he hath obtained for us; he hath instituted and ordained holy mysteries, as pledges of his love, and for a continual remembrance of his death, to our great and endless comfort. To him therefore, with the Father and the Holy Ghost, let us give, as we are most bounden, continual thanks; submitting ourselves wholly to his holy will and pleasure, and studying to serve him in true holiness and righteousness all the days of our life. Amen.
