So why should religious doctrine determine domestic policy in a secular nation? If we let that happen we are no better than half the nations in the Mideast where religious leaders run the country.
You don't get it , BT. The bishops of the RCC don't determine policy for the government.
They determine policy for the church and the requirements for church membership.
And if Sleepy Joe wants to be a member of the RCC in good standing, the bishops of the RCC have a right to enforce the rules. And Biden always has the option of quitting the RCC and joining with Episcopalianism , agnosticism, or other religion if he doesn't want to follow the rules.
