In Christian tradition, the Epiphany feast marks the end of the 12-day Christmas season and celebrates the revelation -- to the whole world -- that Jesus is the Son of God.

Thus, it was highly symbolic when a Muslim participating in an Epiphany rite at St. Mary's (Episcopal) Cathedral in Glasgow, Scotland, chanted verses from the Quran, Surah 19, in which the infant Jesus proclaims:

"Lo! I am the slave of Allah. He hath given me the Scripture and hath appointed me a Prophet. … Peace is on me the day I was born, and the day I die, and the day I shall be raised alive!" The text then adds: "Such was Jesus, son of Mary: a statement of the truth concerning which they doubt. It befitteth not Allah that He should take unto Himself a son."

Cathedral leaders took to social media to hail this as a lovely moment. But in the Church of England, one of the chaplains of Queen Elizabeth II was dismayed by what many would consider an act of blasphemy -- a reading of this clear Islamic denial of Jesus being the Son of God.

The Glasgow rite was justified as "a way of building bridges and a way of educating people," the Rev. Gavin Ashenden told the BBC.

Nevertheless, he argued that it was wrong to insert such a reading into "the Holy Eucharist and particularly a Eucharist whose main intention is to celebrate Christ the word made flesh come into the world. … To choose the reading they chose doubled the error. Of all passages you might have read likely to cause offence, that was one of the most problematic."

After hearing from Buckingham Palace, Ashenden resigned as one the queen's chaplains. Thus, he surrendered his unique status in a land in which the Church of England has been weakened by almost every cultural trend, yet retains a unique niche in the national psyche.

This was, Ashenden said, a matter of personal principle and ancient doctrine.
