The burden of proof lies on those who claim the saints hear us
Nor is it our task to prove the contrary, though much could be brought from Scripture on the point. For us to refrain from begging the prayers and suffrages of departed saints, it is enough that we do not know whether they hear us and do not find it revealed in God's word.
Those who say it is so must prove what they say. They are bound to demonstrate the knowledge of our affairs that they ascribe to the souls of the saints, by an argument that cannot be answered or by some clear word of Scripture. Otherwise their devotion toward the holy souls of the saints will totter altogether and be practiced without faith.
Latin
XCVII. Neque nostrum est contrarium probare; quamvis multa in hanc rem ex Scriptura afferri possent. Nam ut ab implorandis Sanctorum defunctorum precibus atque suffragiis abstinere debeamus, sufficit ut nesciamus an ipsi nos audiant; nec videamus istud in Dei Verbo revelatum. Affirmantibus vero rem ita se habere probandum incumbit quod dicunt; & quam Sanctorum animabus tribuunt rerum nostrarum notitiam, invicto argumento, aut claro aliquo Scripturae oraculo demonstrare tenentur. Alioquin ista ipsorum erga pias Sanctorum animas devotio prorsus nutabit, & absque fide fiet.
