From 1973 to 1979 he met, to receive their advice, some of the best-known spiritual leaders of that era: [[Archimandrite]] (now Saint) [[Justin Popovich]], Archimandrite [[Sophrony (Sakharov)]] and, in two long stays at Mount Athos, the followers of Elder [[Joseph the Hesychast]] - the Elder Ephrem of [[Katounakia Fathers (Athos)|Katounakia]], the Elder [[Ephraim (Moraitis) of Philotheou]], the Elder [[Charalampos (Dionusiates)]] - especially the Elder [[Paisios (Eznepidis)]] with whom he had long talks and whose support remains of great importance to Larchet.
Pr. Larchet has been teaching philosophy for 35 years, and as a patrologist and theologian has lectured in many countries (Argentina, Belgium, Bulgaria, Canada, Cyprus, France, Great Britain, Georgia, Greece, Italy, Luxembourg, Montenegro, Poland, Romania, Russia, Serbia, Slovakia, Spain )
He is one of the very few contemporary authors who is able seamlessly to combine rigorous scholarship with a vibrant sense of the inner life of the Church. His prolific writings on the spirituality of the [[Church Fathers|Fathers of the Church]] and on
orthodox theology ([http://www.editionsducerf.fr/html/fiche/ficheauteur.asp?n_aut=553 twenty-six books], over one hundred and fifty articles) have been translated into no less than 17 languages.<ref>[[Apostoliki Diakonia]].
