This is a kind of a pamphlet by John Williams (1633x6-1709), bishop of Chichester, defending a practice current in the Church of England. He discusses whether divine service should be celebrated in an 'unknown tongue' as was done in the Catholic Church, or whether it should be translated into a language people understand as was done in the Church of England. At the beginning of the discourse, Williams quotes 'Article 24' by the Church of England, which reads as follows: It is a thing plainly repugnant to the Work of God, and the Custome of the Primitive Church, to have publick Prayers in the Church, or to minister the Sacraments in a Tongue not understood of the People'. Refuting what is said in Session 22, Canon 8 of the Council of Trent, the then 'Standard of the Doctrine of the Church of Rome' (p. 2), Williams quotes the same words again at the very end of his 56-page discourse as a conclusion.
The author's name is not printed on the title page or anywhere in this book, but a seemingly early modern hand adds 'by Williams' on the title page of my copy. It was presented to the Library of the Protestant Institute of Scotland by Reverend D. L. A. Aguew from Wigtown on 10 June 1867. Not a very interesting book, and I do not remember why I bought it.
