Canon Richard Dixon: "History of the Church of England," 3:106ff.

The visitations were to abolish the mass and establish the Book of Common Prayer, forthcoming on Whitsunday. Dr. Cox, Dean of Christ’s, Oxford, an active correspondent with Bullinger, welcomed Martyr to Oxford. The Eucharist issue is now a big matter. Martyr lectures on 1 Corinthians, a pacesetter. Before Oxford, Martyr had been a table companion to Cranmer at Lambeth with lengthy discussions on the Eucharist. Contest between Dr. Smith, an old schooler, and Martyr tango. Smith alleges that Martyr may not have been Romanist but was Lutheran (114). Cranmer denies that claim to Smith, to wit, that the Martyr was Reformed on the Eucharist: “On this Cranmer remarks, `Of M. Peter Martyr's opinion and judgment in this matter, no man can better testify than I; forasmuch as he lodged within my house long before he came to Oxford, and I had with him many conferences in that matter, and know that he was then of the same mind that he is now [DPV, to wit, Reformed], and as he defended afterwards openly at Oxford, and hath written in his book. And if D. Smith understood him otherwise in his lectures at the beginning, it was for lack of knowledge (112).’”
