23 Hold fast these traditions undefiled and, keep yourselves free from offense. Sever not yourselves from the Communion; deprive not yourselves, through the pollution of sins, of these Holy and Spiritual Mysteries. And the God of peace sanctify you wholly; and may your spirit, and soul, and body be preserved entire without blame at the coming of our Lord Jesus Christ:— To whom be glory and honour and might, with the Father and the Holy Spirit, now and ever, and world without end. Amen.
