Rome's distinction: absolute prayer to God, relative prayer to the saints as intercessors
The teachers of the Roman Church reply that the prayer Scripture sets forth as part of the worship proper to God is absolute prayer, by which someone is asked as himself the author and giver of good things. It is not relative prayer, by which we ask someone to pray to God for us and obtain from God what we need.
They say they call on angels and saints not as authors of good things but only as those who obtain them for us, our intercessors with God. So they ask nothing more of angels and saints than that they pray to God for us, just as, without any wrong to God, we ask our fellow believers who live with us on earth to help us before God with their prayers.

XC. Respondent Doctores Ecclesiae Romanae Orationem illam quam Scriptura proponit, ut partem cultus qui Deo proprius est, esse orationem absolutam, qua rogatur aliquis, ut ipse bonorum author atque largitor; non autem relativam, qua rogamus aliquem ut Deum pro nobis oret, & ea quibus egemus nobis a Deo impetret: se vero Angelos & Sanctos invocare non ut ipsos bonorum authores; sed solum ut eorundem bonorum impetratores, & nostros apud Deum intercessores: adeoque se non aliud ab Angelis & Sanctis petere quam ut Deum pro nobis orent: quemadmodum absque ulla in Deum injuria, rogamus ipsos fideles nobiscum in terra viventes, ut nos apud Deum precibus suis juvent.
