Tikhon Shevkunov, who heads Moscow's Sretensky Monastery and is widely believed to be the Russian president's spiritual counselor, said on state television Saturday that his church forgave the singers right after their "punk prayer" in the Christ the Savior Cathedral in Moscow in February.
"The church has been sometimes accused of not forgiving them," the bearded and bespectacled cleric said. "We did forgive them from the very start. But such actions should be cut short by society and authorities."
Archpriest Maxim Kozlov agreed, but he also said on state TV that his church hopes the young women and their supporters change their ways.
"We are simply praying and hoping that these young women and all these people shouting in front of the court building, committing sacrilegious acts not only in Russia but in other countries, realize that their acts are awful," he said. "And despite this the church is asking for mercy within the limits of law."
Both clerics supported the court's decision to prosecute the band, despite an international outcry that called it unfair. Governments, including those in the United States, Britain, France and Germany, denounced the sentences as disproportionate.
The case has underlined the vast influence of the Russian Orthodox Church. Although church and state are formally separate, the church identifies itself as the heart of Russian national identity and critics say its strength effectively makes it a quasi-state entity. Some Orthodox groups and many believers had urged strong punishment for an action they consider blasphemous.
The head of the church, Patriarch Kirill, has made no secret of his strong support for Putin, praising his leadership as "God's miracle," and he describing the punk performance as part of an assault by "enemy forces" on the church.
The Orthodox Church said in a statement after Friday's verdict that the band's stunt was a "sacrilege" and a "reflection of rude animosity toward millions of people and their feelings." It also asked the authorities to "show clemency toward the convicted in the hope that they will refrain from new sacrilegious actions."
