Earlier quoted context omitted.
Venerate: 1 to regard with reverential respect or with admiring deference 2 to honor (an icon, a relic) Merriam-Webster. What's the problem with venerating Mary? The Apostolic Church, East and Rome can over come their differences, there's little substantive difference.
Many Catholics believe that Mary was born without sin (immaculate conception), never died (assumption into heaven), can advocate to Jesus for believers (intercession) and has been crowned the Queen of Heaven. This goes well beyond "admiring" or "honoring". To complicate matters, many of these dogmas were only formalized by the Catholic church in the past 200 years. Quite a hard sell for the "sola scriptura" contingen…
So do the Orthodox churches. And both have roots going back way longer that 'just' two hundred years:
> Mary as Queen of Heaven is praised in the Salve Regina ("Hail Queen"), which is sung in the time from Trinity Sunday until the Saturday before the first Sunday of Advent. It is attributed to a German Benedictine monk, Hermann of Reichenau (1013–1054). Traditionally it has been sung in Latin, though many translations exist. In the Middle Ages, Salve Regina offices were held every Saturday.[21]

And if we're going to with potentially troublesome dogmas, I would think the Real Presence would be much higher on the list:
