Where do we get the notion that the saints have special rights or powers to grant things we ask of them.
From Sacred Tradition.
Isn’t that then a form of worship?
The problem is that worship, as understood in colloquial English, isn’t a particularly precise term.
Fr. Hardon defined worship as follows:
Acknowledgment of another’s worth, dignity, or superior position. In religion, worship is given either to God, and then it is adoration, or to the angels and saints, and it is called veneration. Divine worship actually includes three principal acts, namely adoratin (or the recognition of God’s infinite perfection), prayer or the asking for divine help, and sacrifice or the offering of something precious to God. Worship as veneration also has three principal forms, whereby the angels and saints are honored for their sanctity, asked to intercede before the divine Majesty, and imitated in their love and service of God. (Etym. Old English weorthscipe, honor, dignity, reverence: weorth, worth +ship.)
In a certain sense, yes, we do worship Saints. In fact, older texts or manuals or prayers might say as much. To worship something is simply to acknowledge that it has a certain worth.
However, most people today use the verb to worship only in the sense of adoration. In that sense, we do not worship Saints, and praying to them is not a form of adoration. Here is Fr. Hardon’s definition of adoration:
The act of religion by which God is recognized as alone worthy of supreme honor because he is infinitely perfect, has supreme dominion over humans, and the right to human total dependence on the Creator. It is at once an act of mind and will, expressing itself in appropriate prayers, postures of praise, and acts of reverence and sacrifice. (Etym. Latin ad- to + orare, to pray; or os, oris, mouth, from the pagan custom of expressing preference for a god by wafting a kiss to the statue: adoratio, worship, veneration.)
None of the above applied to praying to Saints. When I pray to St. Therese, I’m not recognizing her as “alone worth of supreme honor” nor do I think she “has supreme dominion over humans.” I am simply communicating to her in a supernatural way.
[Isn’t it worship to ask a Saint] to do things to us rather than plead on our behalf TO God?
I can ask a human being to pray for me, and I can also ask him to do something for me. It’s no different with the Saints. God DOES give Saints an ability to influence our lives beyond merely praying for us. Why? Because He wants to. Why not? Why would he give my surgeon the ability to operate on my spine, but not simply heal me Himself? Why would He create us as social beings full stop? Because, clearly, that’s the best way to do things. Is there anything obviously unreasonable about that?
Why not ask Jesus to defend us in battle rather than St Michael?
Why not ask Jesus this question yourself rather than relying on me (or anyone else reading this thread) to respond? Because we clearly live in a universe wherein God has set up delegates.
Isn’t St michael under the control of God anyway?
St. Michael has free will, of course. Likewise, all of his power was given to him by God. But don’t you think he can exercise this free will and power in a manner that is both consistent with God’s will and which is to our benefit? Is that unreasonable? Of course not: it’s the most reasonable thing in the world, and we see it every day all around us. Is any human being more intelligent or wise than God? Of course not! Then why do we bother asking them things? Because God gave them gifts, and God always gives gifts so that they can be shared with others. So it is with us, so it is with the Saints.
Lastly, while some apologists make this distinction between praying TO Saints and asking them to pray for us, I consider this antics with semantics. Yes, we pray TO Saints in the same what I am typing TO you. No, that does not imply we believe the Saints to be somehow more powerful than God.
