Elsie:
But the article by Msg. Pope was written to Catholics and the Liturgical Texts at last Sunday’s Mass were Isaiah 22:20-24 from the OT and Matthew 16:16-18. Msg. Pope’s blog is for Catholics wanting to get a solid explanation on the Liturgical Readings and this one related to the role of the Pope and thus how those 2 Scripture text are understood in Catholic ecclesiology and in particular to the role of the Pope [Bishop of Rome]. So yes, in the Catholicism, there is One Pope and I nor any other Catholic not the Pope [because he is the Pope] is it.
So; if I read you right; there are Catholics that do not know there is only one pope, and it had to be repeated, WORLDWIDE, to those who have been, evidently, poorly catechized?
