As, metropolitan Boretsky composed a petition in defense of the Orthodox hierarchy entitled Protestacja (1621). Along with the Greek-Catholic Metropolitan bishop of Kyiv Josyf Veliamyn Rutsky, he favoured a general reconciliation within the Ukrainian church, but failed to gain the support of the Cossacks for his plans. A prolific translator, Boretsky also wrote poems honouring saints, petitions, prefaces, and edicts. "Perestoroha" is attributed to him. He was the co-author of "Apolleia Apolohii" (A Refutation of 'A Defense,' 1628) and the translator of "Antolohion" from the Greek (1619).
