   By the end of the 530s, as noted above (2.1), Philoponus seems to have stopped fighting philosophical battles altogether; his career as a philosopher was over. Thenceforward he devoted himself solely to writing on Christian theological topics. Since there is no evidence that he belonged to the clerical order, it is difficult to imagine the institutional context of his life as a Christian theologian. He published his theological treatises under the same name by which he had established himself as a commentator, Iôánnês ho Grammatikós, yet it seems hard to imagine him still working as a professor of grammar or literature in the Alexandrian system of higher education. His other epithet, ‘philóponos’ (lover of toil) is probably best interpreted as an acknowledgment of his literary productivity, although it may also be an indication that he was one of a group of zealous Christian brethren in Egypt who called themselves by that name.
