Some fathers of the fourth and later centuries protested against Gnostic phylacteries worn by Christians. Various phylacteries appear in the tracery. In the tracery are various phylacteries some held by angels. Since the 1970s, formerly excised blessings (like those on phylacteries) were returned. Neither Aquila nor Symmachus use "phylacteries" in their translations. None should presume to hang any phylacteries from the neck of man nor beast.
