Note 1415 — XXIX. THE POST-TRIDENTINE CHURCH.

By a Bull dated July 18, 1564, Pius IV. fixed May 1, 1564, as the time when the Tridentine canons became the law of the church. His letter to the Archbishop of Bremen with an official copy and directions as to its promulgation, is dated Oct. 3d of the same year (Hartzheim VII. 25).

It would seem to be a work of supererogation for a learned Italian lawyer to write an elaborate treatise, dedicated to Pius IV., against the abolition of celibacy, yet Marquardo dei Susani thought it worth while to do this in his “Tractatus de Cœlibatu Sacerdotum non abrogando,” 4to. Venice, 1565.
