So you only go the churchhouse to "venerate" (proskuneo = bow or kneel in hmage to) her -- that is, her image there?
Even regarding (an) angel(s), even in a waking vision, the Beloved John was commanded NOT to do this kind of "voluntary humility" (Col. 2:18-19) which is exactly what you try to make out veneration to be:
"And I fell at his feet to worship* him. And he said unto me, See thou do it* not: I am thy fellowservant~, and of thy brethren that have the testimony of Jesus: worship* God: for the testimony of Jesus is the spirit of prophecy (Rev. 19:10 AV; * = proskuneo, ~ = co-slave).
Mary, though worthy of honor, is still a co-slave with us of Jesus, whom she gave birth to, but of whose actual sinful desoxyribonucleic acid He is not.
Here's what happens: Despite all the fine weasel words you sling about regarding "veneration," and regardless of how careful the catechumen is instructed, he/she is going to be overwhelmed by the supererogatory necessity of emphasizing the value of the special consideration accorded the person and role of Mary, both then and now, supposed halo and all.
That spiritually waterboarded novitiate is, lifelong, going to overcompensate the "veneration" that you teach, will never want to be found at all short in that area od humility, and is going to overcompensate by falling into the worship mode, never able to determine where the fine line between "venerate" and "bow or kneel in homage" exists (if at all, and who is to say?), always performing execrable idolatry, which is just beyond respectful regard.
To me, all your scripturally-unsupported rationale is just a wagon-load of what my grandfather farmer spread the fields with. And that is why in English, the word worship is the definition of only two words, one in Hebrew and one in Greek, of W-O-R-S-H-I-P; and to which in either your DRB or my KJV never is assigned the alphabetic value of v-e-n-e-r-a-t-i-o-n.
Let's be done with this impractical catechistic hocus-pocus word-bandying, eh? And get down to whether Catholics have been following the determined will, the thelema (θέλημα) of The Father and His Son (Heb. 10:9-10) in its historical development.

We only go to the church house to venerate (duleo) Mary? No. I don’t understand what you mean by this.
