This catechism (it may be remarked) has been sometimes confounded with the short form contained in our Prayer Book. The latter, however, was of genuine English growth, though of doubtful origin: Strype assigns it expressly to Nowell;[362] but the modern biographer of the Dean of St. Paul’s questions his title to it, and rather gives it to Poinet, afterwards Bishop of Winchester.[363] In any case, Cranmer appears to have reviewed and digested it, not without the able co-operation of Ridley.[364] It made a part of the Liturgy of King Edward, of which more will be said in its proper place, being inserted in the Office for Confirmation. Nor has any material change been since introduced into it, except that the explanation of the Sacraments was added in the reign of James I., the original Catechism having ended with the Exposition of the Lord’s Prayer. The same year, 1548, came out another work, by which the cause of the Reformation was still more essentially served, and the structure of the church advanced, the _Office of the Communion_. It was compiled chiefly out of the Roman missal, of which it is often a literal translation, by “sundry of his Majesty’s most grave and well-learned prelates and other learned men in the Scriptures,” and in its first shape retained (so it was afterwards thought) some particulars of its original, which would have been better modified or suppressed. It underwent like the other Offices of which more will be said presently, a rigid revision by Martyr and Bucer before its re-appearance in 1552, for the benefit of whose remarks the whole was turned into Latin (so pains-taking were the founders of our Church); and prayer for the dead, the invocation of the Holy Ghost upon the elements, and a certain bias, or what might have been mistaken for such, towards the real presence, were corrected, but with a delicate hand and admirable judgment though they were still in after-times those amongst the non-jurors who maintained that the changes were not to its advantage; and even Laud, it has been observed, in the composition of his Liturgy for the episcopalian church of Scotland, has in some things shown a preference to the first over the amended form.[365]
