The Scripture readings for today’s liturgy provide a biblical basis for the papacy, as John Bergsma explains.

Yesterday, June 29, was the Solemnity of Sts. Peter and Paul. In recent years it has become a custom for the Pope and the Patriarch of Constantinople to exchange official delegations on the patronal feasts of their respective sees.

I challenged Jason to make his case from the Greek text, but he has yet to respond. Some readers, [...]
