Gillespie in his Assertion of the Government of the Church of Scotland notes the following:
The office of the popish priest stands in two things, to consecrate and offer up the body of Christ, and to absolve the faithful from their sins. ... And the same two make up the proper office of the priest by the order of the English Service-Book.
My guess would have been Laud's Service book, but I couldn't find a chapter on the office and in later editions I can really find enough to conclude these two points. There is a 1712 reprint to Laud's book online but I'm not sure the 1637 is.
