Praying to Saints in the same forms used to God is treason against the divine majesty
Using toward the Saints the same prayer-forms used toward God, and asking them for grace, glory, and any bodily or spiritual good, is treated as an offense against God's majesty.
It does not help to call the Saints not the first authors but only givers and stewards under God.
The same pretext would not excuse sacrificing to them.
Latin
XXIX. Denique non existimant illos effugere crimen laesae majestatis divinae, qui in suis precibus iisdem formulis Sanctos compellant atque Deum, poscentes ab iis gratiam & gloriam, ac bona quaelibet corporis & animae: licet non habeant Sanctos pro primis bonorum illorum authoribus, sed solum tanquam eorum sub Deo largitores & administratores: sicuti crimen illud non effugeret, qui sub praetextu simili Sanctis immolare vellet.
