We heard today that roving gangs of cyber-bullying Catholics are a problem in terms of the institutional Church. Indeed, we heard today that this has ecclesiological consequences. Even assuming that this is not the continuation of a Twitter beef in highfalutin terms, an assumption we ourselves would not readily make, the assertion is a little silly. (The author mostly seems to complain about anyone interested in orthodoxy qua orthodoxy, since he also complains about the Holy Office in the 1950s under the great Cardinal Ottaviani.) In this context, Pius IX’s 1863 Letter to Archbishop von Döllinger of Munich, Tuas libenter, makes an extraordinarily interesting point:

Dum vero debitas illis deferimus laudes, quod professi sint veritatem, quae ex catholicae fidei obligatione necessario oritur, persuadere Nobis volumus, noluisse obligationem, qua catholici Magistri ac Scriptores omnino adstringuntur, coarctare in iis tantum, quae ab infallibili Ecclesiae iudicio veluti fidei dogmata ab omnibus credenda proponuntur. Atque etiam Nobis persuademus, ipsos noluisse declarare, perfectam illam erga revelatas veritates adhaesionem, quam agnoverunt necessariam omnino esse ad verum scientiarum progressum assequendum et ad errores confutandos, obtineri posse, si dumtaxat Dogmatibus ab Ecclesia expresse definitis fides et obsequium adhibeatur. Namque etiamsi ageretur de illa subiectione, quae fidei divinae actu est praestanda, limitanda tamen non esset ad ea, quae expressis, oecumenicorum Conciliorum aut Romanorum Pontificum, huiusque Apostolicae Sedis decretis definita sunt, sed ad ea quoque extendenda quae ordinario totius Ecclesiae per orbem dispersae magisterio tanquam divinitus revelata traduntur, ideoque universali et constanti consensu a catholicis Theologis ad fidem pertinere retinentur.

(Emphasis supplied.) A translation may be found at DH 2879. The Second Vatican Council cites Tuas libenter in a note to Lumen gentium 25. We would also direct the interested reader to Ford and Grisez’s 1978 essay, Contraception and the Infallibility of the Ordinary Magisterium, pages 274 and 275.

Food for thought, no?
