VERSUS
FRANCISCO SUAREZ, S.J. (1548-1617)
CALLED BY POPE PAUL V DOCTOR EXIMIUS ET PIUS (MOST EXALTED AND PIOUS)
"Et hoc secundo modo posset Papa esse schismaticus, si nollet tenere cum toto Ecclesiae corpore unionem et coniunctionem quam debet, ut si tentat et totem Ecclesiam excommunicare, aut si vellet omnes Ecclesiasticas caeremonias apostolica traditione firmatas evertere. (De Charitate, Disputatio XII de Schismate, sectio 1) >p> "And in this second way the Pope could be schismatic, if he were unwilling to be in normal union with the whole body of the Church, as would occur if he attempted to excommunicate the whole Church, or, as both Cajetan and Torquemada observe, if he wished to overturn the rites of the Church based on Apostolic Tradition."
58. It follows from this that the Sovereign Pontiff alone enjoys the right to recognize and establish any practice touching the worship of God, to introduce and approve new rites, as also to modify those he judges to require modification.[50] (Pius XII, Mediator Dei)
It furthermore declares, that this power has ever been in the Church, that, in the dispensation of the sacraments, their substance being untouched, it may ordain,--or change, what things soever it may judge most expedient, for the profit of those who receive, or for the veneration of the said sacraments, according to the difference of circumstances, times, and places. (Council of Trent, Sess. XXII Ch. II)
