Warning: The following is not a “whataboutism” comparison between Joe Biden and Vladimir Putin or an attempt to find some kind of moral equivalence between their policies and actions.

What I am doing is making a comment about what journalists can and cannot know about a leader’s public and private religious convictions. This is a key theme in this week’s “Crossroads” podcast (CLICK HERE to tune that in) about religious issues linked to Putin’s invasion of Ukraine. The big idea is that politicians in a variety of cultures are skilled, when it comes to using religious themes and symbols.

First, what do we know about Biden’s Catholic beliefs?

We know that he carries a rosary, knows how to use it and frequently attends Mass, almost always in parishes sympathetic to him. We know that ancient doctrines in Catholic moral theology are important to him when it comes to immigration and social justice issues, but not when it comes to marriage, abortion, sexual ethics and, until recently, the death penalty.

What does this tell us about what he does or does not say during Confession and other crucial issues about the content of his faith? Next to nothing. Thus, his actions are crucial.

Now, what do we know about Putin’s Orthodox beliefs?

We know that he built a chapel near his office, that he knows how to make the sign of the cross and light prayer candles. We know that he believes that Orthodox Christianity is a crucial part of Russian history and that “Holy Mother Russia” is an important concept in Russian identity and nationalism. We know that issues such as abortion and marriage formation were not important to him — until it became clear that Russia is in a state of demographic collapse. Putin has, of course, used major themes from Orthodox history to justify his actions in Ukraine.

We also know that his government and his supporters have poured oceans of money into the rebuilding of Orthodox churches in the post-Soviet era, believing that this is in the national interest. This matters in a nation that endured the most sweeping wave of martyrdom in Christian history, with the closing of 98% of the land’s churches, the murder of 200,000 bishops, priests and nuns and millions of others in death camps, purges, planned famines (in Ukraine, especially) and other forms of persecution. We know that some clergy were crucified on the doors of their churches, slaughtered on their altars or stripped naked, doused with water and left outdoors in winter.

What does this tell us about what Putin does or does not say during Confession and other crucial issues about the content of his faith? Next to nothing. Thus, his actions are crucial.
