He was a renaissance man who had studied art and music in his younger years, a leader with a developed political conscious who was a member of the Organization of Ukrainian Nationalists in the 1930s.

In 1989 he and the other members of the clergy left the Moscow Patriarchate and declared to be put under the omophor of the Ukrainian Autocephalous Orthodox Church under Metropolitan Mstyslav (Skrypnyk) who was at that time the head of the Ukrainian Autocephalous Orthodox Church in USA and Canada.

Dymitry Yarema initiated and was a participant in the first All-Ukrainian Sobor of the UAOC, held in Kyiv in 1990, which elected Metropolitan Mstyslav as the first patriarch of Ukraine.

In 1993 he took his monastic vows and then was ordained bishop of Pereyaslav and Sicheslav by Archbishop of Lviv Petro (Petrus).

In late 1998 the aging Patriarch Dymytriy, his health weakening, determined that the future of the Church would be strengthen if it would turn once again to the Ukrainian diaspora, which had maintained the UAOC during nearly 70 years of Communist rule in Ukraine.
