Ukrainian draft officers detained Metropolitan Sergius of the Ukrainian Orthodox Church (UOC) on Sunday, a lawyer for the church said, in the latest escalation of Kiev’s long-running crackdown on the country’s largest denomination.

Ukraine’s conscription drive has grown increasingly violent and corrupt as it attempts to make up for battlefield losses and with the supply of willing recruits long since exhausted. Regional mobilization officials have been detained on charges of taking bribes for deferments, and the threat of being pressed into military service has reportedly been used to pressure journalists to not publish damning reports.

Sergius heads the UOC’s Tulchin diocese in Vinnitsa Region. Draft officers detained him, along with Archpriest Anatoly Vishnev, in southeastern Kiev, according to a Telegram statement by Archpriest Nikita Chekman, a lawyer who represents the UOC.

Both were taken for medical evaluations at the local Territorial Center of Recruitment and Social Support (TCK), the body tasked with overseeing Ukraine’s conscription drive, according to the lawyer.

Sergius was released later in the day, but his passport was seized, Chekman said in an update.

Both the detention and the seizure were carried out “without proper procedural formalities,” with no paperwork or legal basis provided for either action, he said, adding that the UOC considers the TCK’s actions unlawful.

Conscription officers were still attempting to process Archpriest Vishnev as of Sunday evening, Chekman added.

Our team will take all measures provided by law to challenge the unlawful detention, confiscation of the passport, and illegal mobilization of the clergyman.

Since the escalation of the Ukraine conflict in 2022, Ukrainian authorities have imposed sanctions on UOC clergy, raided its monasteries and churches, and backed efforts to transfer its properties to the Kiev-affiliated Orthodox Church of Ukraine (OCU). The schismatic organization was launched in 2019 under then-President Pyotr Poroshenko.

Forced conscription has reportedly been used to pressure UOC priests.

Moscow, meanwhile, has called it an attempt to “destroy Orthodoxy in Ukraine.”

In late June, Russian Foreign Ministry spokeswoman Maria Zakharova condemned plans to rebury prominent Ukrainian political figures at the Kiev Pechersk Lavra, accusing the authorities of using the iconic monastery to promote “anti-heroes disguised as heroes.”

The head of the Ukrainian Institute of National Remembrance, Aleksandr Alferov, who previously served as a spokesman for the neo-Nazi Azov unit, said last month that the government plans to establish what he called a national “Pantheon” at the Lavra.

Ukraine’s state-level veneration of World War II Nazi collaborators and nationalists has long drawn harsh condemnation from Russia. Moscow has made the “denazification” of Ukraine on of the key goals of its military operation.
