Nevertheless, his efforts in defending Christianity earned him a noble title from the Austrian emperors, and he took up several important positions within the Roman Catholic ecclesiastical hierarchy.

Receiving papal support, Parchevich visited the royal courts of Europe and advocated the formation of an anti-Ottoman alliance which would drive out the Ottoman Turks from the Balkans.

[2] Along with the Diocese of Nicopoli headed by Filip Stanislavov, Marcianopolis was one of the two sees which succeeded the Bulgarian Custody as the governing body of Catholicism in Bulgaria.

[2] In 1661, Parchevich had to step down as Archbishop of Marcianopolis due to pressure from Rome, which condemned his clerical inactivity,[4] though in 1668 he became apostolic vicar to Moldavia[2][5] despite continuing suspicion.

His plans were backed by the rulers of the Romanian lands which border Bulgaria north of the Danube: Gheorghe Ştefan of Moldavia and Constantin Şerban of Wallachia.

While on a diplomatic mission to Pope Clement X,[7] he died of illness[3] in Rome in the summer of 1674 and was buried at the Sant'Andrea delle Fratte basilica in the city.

[11] In addition, three schools, in Plovdiv, Rakovski and Chiprovtsi, are named after him,[12] as is a community centre (chitalishte) in the Banat Bulgarian village of Asenovo, Pleven Province.
