I told ChatGPT: Write a short prayer for Christian unity in the style of the Book of Common Prayer, 1662.

Result: O merciful God, who hast taught us in thy holy Word, that thou dost not delight in division, but in the unity of thy Church: grant, we beseech thee, unto thy whole Church in paradise and on earth, that, being all joined together in the same faith and in the same love, they may be united in heart and in soul, and may be one, as thou and thy Son Jesus Christ are one; who with thee and the Holy Ghost liveth and reigneth, one God, world without end. Amen.
