ABS, I do agree with you that at one time the idea of having two or more supreme subjects was confined to the City of Man and manifestly popularised by the beautiful and talented three member girl group from Motown, The Supremes, led by Diana Ross, but in their wisdom, during the most recent ecumenical council, the Fathers at that council taught in Lumen Gentium that there are now two subjects which are to be considered as possessing full supreme and universal power - the Pope and the College of Bishops - and so we can be thankful that the church, in her prudential wisdom, has grabbed a cot, as it were, in the battlefield tent hospital pitched on a downtown Mall parking lot in the midst of the City of Man, and has kicked-back, relaxed, and has abandoned the stressful matter of having always to adhere to the principle of non-contradiction (Who says only one subject can be supreme?) and so we can relax not only in that area but now, as we now know, the continuity remains even in the midst of captious controversies and as a Professor of the hermeneutics of continuity I am always constrained to note that even when it appears that the Holy Father has a praxis 180 degrees in opposition to what the previous 265 Popes have done and taught, that is no cause for concern for he is the 266th Pope and America, the home of the super group, the Supremes, has had only 45 Presidents, and they are way more in disagreement with one another than Pope Francis is in disagreement, one imagines, with the 265 Popes who proceeded him; so not to worry, ABS, the continuity resides in the Papacy no matter what his praxis is and even if he be a dream and deal breaker; indeed, especially when he does what no other Pope has ever done is that continuity manifested, maintained, and even, I dare say, mutilated, owing to Mercy.
O, the College of Bishops, who also have full, supreme, and universal power? Well, ABS, this Professor notes The College is on a grade-yourself marking system and it is now on an extended quarterly trimester break. Amen?
