The city of Athens at this time was full of dangerous distractions for young men; feasts, theatres, assemblies, wine parties, etc.  Gregory and his friend resolved to renounce all these, and to allow themselves to know only two roads—one, that which led to the Church and its holy teachers; the other, that which took them to their University lectures.  Amongst other famous students of Gregory’s day was Prince Julian, afterwards the Emperor who apostatized and endeavoured to restore the ancient heathenism, and galvanize it into something like a new life.  Gregory claims even at this early period to have foreseen and dreaded the result of Julian’s accession.  “I had long foreseen,” he says, “how matters would be, from the time that I was with him at Athens.  He had come there shortly after the violent measures against his brother, having asked permission of the Emperor to do so.  He had two reasons for this sojourn—the one more honest, namely, to visit Greece and its schools, the other more secret and known only to a few persons, namely, to consult with the heathen priests and charlatans about his plans, because his wickedness was not as yet declared.  Even then I made no bad guess about the man, although I am not one of those skilled in such matters; but I was made a prophet by the unevenness of his disposition and the very unsettled condition of his mind.  I used these very words about him:  ‘What an evil the Roman State is nourishing,’  though I prefaced them with a wish that I might prove a false prophet.” (Orat. V. 23, 24.)  Gregory must have been a long time at Athens.  He seems to have gone there at about the age of eighteen, and not to have left till he was past thirty.  Basil left before him and returned to Cappadocia, and as soon as he could follow he went to Constantinople, where he met his brother, who had just come there to practice as a Court Physician, but resolved to throw up his practice and return with his brother to Nazianzus.  They found their parents still living and their father occupying the Episcopal Throne.  From this time onward Gregory divided his time between his parents and his friend, living partly at Arianzus, and partly with Basil in Pontus, in monastic seclusion.  At his Baptism, which it seems most probable took place at this period, he made a solemn vow never to swear, and to devote his whole energies and powers solely to the glory of God, and the defence and spreading of the faith.  Cæsarius did not remain long in the retirement of home, but soon returned to the Capital, where a brilliant career seemed opening before him.  Gregory, whose mind was strongly impressed with the dangers and temptations of a life at Court, did not altogether approve of this step, yet he does not very severely blame it.  He himself, however, felt very strongly drawn to the monastic life; but as retirement from the world did not seem to him to be his vocation, he resolved to continue to live in the world, and to be a help and support to his now aged parents, and especially to his father in the duties of his Episcopate, but at the same time to live under the strictest ascetic rule.  He had, however, always a secret hankering after the Solitary life, which he had once (Ep. i.) promised Basil to share with him; and he did find himself able for some years to spend part of his time with his friend in his retirement in the wilds of Pontus.  They portioned out their days very carefully between prayer, meditation and study, and manual labour, on the principles laid down by Basil in a letter to his friend, which afterwards were developed into the celebrated Rule still observed by the entire body of the Religious of the Eastern Church.  Retirement, he says, does not consist in the act of removal from the world in bodily presence, but in this, that we tear away the soul from those bodily influences which stir up the passions; that we give up our parental city and our father’s house, our possessions and goods, friendship and wedlock, business and profession, art and science, and everything, and are quite ready to take into our hearts nothing but the impressions of the divine teaching.
