Well there is a fundamental disagreement here between the Roman Catholic and evangelical Christian communities. Evangelicals take the keys as the authority that congregational leaders get from faithful obedience to the Holy Spirit. Roman Catholics see it tied to ecclesiastical offices connected to their physical lineage. (Evangelicals believe in spiritual lineage to the church via its witness from founding times, to wit the bible.) As a ‘crazy’ evangelical I reveal my bias in the dispute. It’s a bit difficult, to me, to explain the spectacular success of gospel in evangelical churches as being a mere side effect of the existence of the Roman Catholic church, when its luminaries have been busy damning such evangelical churches since Luther stuck his objections up on the Wittenberg door... and trying to explain it away as mere deviltry doesn’t work very well either.
We may disagree on some points (!), but we are all Christians.
