Chief cult-part: invocation—Saints know at least what touches their beatitude, including living prayers for their help
Invocation is the chief Roman cult of Saints and Angels—spoken aloud or by heart alone.
School premise: reigning Saints need not know all earthly events, yet know what touches their beatitude—including cult and pleas for their aid.
Hence it is certain for them that the dead Saints hear the living’s prayers.
Next frontier is Romana XLI–LXXVII (how they hear; merits; patrons; Marian dominion), then Pars Secunda Reformata.
Latin
XL. Sed praecipua pars cultus qui Sanctis hominibus & Angelis impenditur in Ecclesia Romana consistit in eorum invocatione, & precibus quae ad illos diriguntur, tum voce, tum etiam solo cordis affectu, & interna mentis loquela. Qua de re ut accuratius teneatur Scholae Romanae Doctrina, observandum est Theologos illius communiter supponere Sanctos cum Christo regnantes, non quidem omnia & singula quae hic geruntur nosse; sed ea saltem omnia quae ad ipsorum beatitudinem pertinent & faciunt. Ad Sanctorum autem Beatitudinem facere existimant, ut noscant cultum qui illis exhibetur, & preces ac orationes, quibus fideles in terris degentes ad eorum opem confugiunt. Ac proinde apud istos Theologos certum est, Sanctos defunctos viventium preces percipere & intelligere.
