In 1845 he was Boyle lecturer and Warburton lecturer.
In 1248 he returned to Cologne with Albertus, and was appointed second lecturer and magister studentium.
If the offer was made, it was declined, and Cranmer continued at Cambridge filling the offices of lecturer in divinity at his own college and of public examiner in divinity to the university.
For fifteen years he continued to labour in this position, his fame as writer and lecturer steadily increasing.
Bishop Williams, a kinsman of Cromwell's, relates at this time that he was "a common spokesman for sectaries, and maintained their part with great stubbornness"; and his earliest extant letter (in 1635) is an appeal for subscriptions for a puritan lecturer.
