_Insuper_, tu jurabis quod nullas conclusiones per fratrem Wilhelmum Russell, ordinis Minorum, nuper positas et praedicatas, contra decimas personales, et in nostra Universitate Oxoniae, necnon in venerabili concilio episcoporum, anno Domini millesimo quadringentesimo vicesimo quinto celebrato Londoniis, solemniter damnatas, nec alicujus earum sententiam tenebis, docebis, vel defendes efficaciter publice aut occulte, nec aliquem doctorem, tentorem vel defensorem hujusmodi, ope, consilio vel favore juvabis[559]. For a similar offence another Franciscan, William Melton, D.D., was arrested at the instance of the University, and compelled to recant[560]. The Alma Mater kept a vigilant eye on her sons wherever they might be. In 1482 Friar Isaac Cusack, D.D., began to create disturbances in Ireland by preaching the old Franciscan doctrine of evangelical poverty; he was captured, sent to Oxford, and degraded and expelled the University as a vagabond and a heretic[561]. The feeling of nationality fostered by the long French wars was not without its influence on the friars in England and especially at the Universities. In 1369 the Chancellor caused a royal proclamation to be published at Carfax ordering all French students at Oxford, both religious and secular, to leave the kingdom[562]. In 1388 a royal writ was issued to the Warden of the Friars Minors in Oxford at the advice of the same convent, warning him to admit no foreign friars who might reveal to the enemy ‘the secrets and counsel of our kingdom,’ and to expel any such friars for whose good behaviour he would not be responsible, or who would not pray or celebrate masses for the King and the good estate of the realm[563].
