1 Timothy. St. Paul here refers to "Mediator" using (in the original text) the highly specific term mesites which means a person holding a favorable position between both parties at enmity who is equally the friend of each. Christ is unique in that His mediation is both in the order of being (through the Incarnation) and in the order of action (the redemptive act of Calvary). It uniqueness derives from the fact that only Christ is both God and Man.
The term used by St. Paul does not exclude the presence or action of lesser mediators acting only on the human level -- i.e., by their willing response to grace. Herein, the Holy Virgin is given the title "Mediatrix" by the Church because her action on the human level in response to grace was absolutely unique in human history. As St. Cyril of Jerusalem (d. 386) says in addressing her, "through you, the only Son of God, source of all light, has shone upon the eyes of the blind, who were sitting in the shadow of death."
Hebrews 9, Hebrews 14, Exodus 20. There is nothing in these statements inconsistent with the notion of lesser mediators.
This discussion is quite an object lesson. Primarily it demonstrates the error of relying on translations, particularly, say, agenda-driven translations of the early 17th Century. As the maxim goes, "Every translation is an interpretation." The original text must be analyzed to fully understand what is being said.
You can call it mediation and veneration ,but if you rely on it for your salvation (as you do in your quote)....pray to it ,make icons of it kneel before it, put flowers and candles before it...publish thanksgiving to it in the paper it is a god..
Um, actually, it's not my quote. It's a quote of St. Ignatius of Antioch, one of the earliest Christian martyrs.
And if he relied on Mary to go to heaven he now burns in hell...not pleasant but true
There is ONE mediator...you can weave and dodge but it ain't Mary.There is no proof of her Assumption...she was a good and holy woman but not sinless and not assumed like a demigod to heaven..she is not another Christ ,she is nor a co redeemer.
