His Beatitude Ieronymos (Jerome), was born in Oenophyta, Boeotia in 1938. His civil name is John Liapis. He studied Archaeology & Theology at Athens University. He enrolled in graduate studies at the University of Gratz, Austria & Munich, Germany. He worked as a Fellow Professor at the Athens Archaeological Society & later as a Teacher at the Leonteios School of Athens, at the 9th Athens Night School & at the Avlona High School. Shortly after his ordination to the priesthood, he became Chief Secretary of the Metropolis of Thebes & Levadeia (1967-1978). He also served as Igumen of the Holy Monastery of Sagmata (Transfiguration of the Saviour) from 1971-1977, and of Hosios Loukas (1977-1981). From 1978-1981 he became the Chief Secretary of the Holy Synod of the Church of Greece. In 1981 he was elected unanimously Bishop of Thebes & Levadia, a post he holds until now (his election as Archbishop of Athens).
From the 110 presbyters of his Diocese, 82 are University graduates, some of Theology & Philology, while others are Architechts, MD, Agronomists, Palaeographers, Information Engineers, or have studied Finance. Among them, a university professor (school of Theology, University of Athens), a university lecturer (school of Theology, University of Athens), and three doctors of Theology (ie doctors of divinity). Under his care, monasticism in his Diosece has flourished (my note: this is exactly what I have heard about him. He is very pro-monasticism). Under his care, in his Diocese, six male monasteries (45 monks) & seventeen female convents (110 nuns) are fully functional. His social work is also very noticable. He has founded an orphanage (at Thebes), two elderly houses (at Thebes & Levadeia), a rehabilitation centre for the mentally ill (at Levadeia), a rehabilitation medicine & vocational centre for the physically handicapped (at Levadia), a rehabilitation centre for the drug addicts (at Levadia), Family Consultative Centres (at Thebes), a Centre for Historical & Archaeological Studies (Holy Monastery of Lycourese at Zaltsa). After his initiative & under his supervision, his eminence has founded the Centre Of Historical & Cultural Studies of Boetia, in collaboration with the Durham & Cambridge Univ (United Kingdom).
