I think most who don't agree with the Title Co-Redemptrix view it as a title of equality with Jesus. That is an incorrect view. iMO, the Church should combat the misinformation rather than retreat from the Title.
Except your church never
dogmatized that title. Also pushing for this would create yet another impediment to unity with the Orthodox - no one liturgically venerates the Theotokos as much as we do (Most Holy Theotokos, save us)*, but we already have an issue of division over the Immaculate Heart devotion and the Immaculate conception (that the Blessed Virgin Mary is immaculate is not disputed - our hymns describe her as such, but our model of original sin, which is based on St. John Cassian’s refutation of Pelagius and used to predominate in the West as well as the East does not require the Theotokos to have been conceived immaculately in order to be sinless, without endorsing Pelagianism).
Also its worth noting the birth of the Theotokos is already a miracle, since Saints Joachim and Anna, the Grandparents of God, were childless due either to infertility on the part Joachim or Anna until the conception of the Blessed Virgin Mary well past the age when St. Anna was potentially pregnant.
The chief difference between Orthodox and Roman Catholic devotions to the Theotokos is that we avoid mental visualization such as in the Rosary (we try to avoid this in prayer in general as it has proven to be problematic, which I can attest to from my own life experiences - the Holy Icons are all the visualization we need for prayer - and is more precise, and longer, and more liturgical, and at the same time more enthusiastic and pervasive.
We don’t just refer to her as St. Mary in the liturgy, for example, but as “our most glorious Lady Theotokos and ever virgin Mary”, and if I were to quote all of the Theotokia, the hymns to the Theotokos, especially the Stavrotheotokia, it would fill a book, and that’s in addition to the Akathists and Molebens.
Also I would note that what I have said largely applies to the more Byzantinized Ukrainian Greek Catholics in North America, but less so in Ukraine where certain differences in use still apply - there are some Ukrainian Greek Catholic churches here like St. Elias who follow the Typikon so precisely as to be indistinguishable from the Orthodox aside from the petitions for the Pope in the Great Litany and his commemoration in the Diptychs (and also for some reason Roman Catholic translations of the Divine Liturgy in my experience do not use the phrase “unto ages of ages” used by most Eastern Orthodox, except for the Ruthenian converts of the American Carpatho Rusyn Orthodox Diocese, and by the Copts.
* I base this statement on the number of liturgical and devotional services and their duration, such as the Akathist and Moleben, and the canons of the Theotokos and the frequency and diversity of the Theotokion hymns in our liturgy, and the fact that the Eastern Orthodox and Oriental Orthodox have been celebrating the Assumption or Dormition of Our Lady since the very early church and have regarded it as dogma this entire time; it did not require a Papal decree in the 1950s for it was for us dogma at least as far back as the fourth century when liturgical evidence of it starts to appear, making it as old in attestation as the Roman Canon.
In contrast the Roman Little Office of the Blessed Virgin Mary, which is beautiful, is now seldom celebrated, and I am not aware of public celebrations of it, and the public rosaries and novenas are not technically liturgical services according to the Western definition of liturgical (interestingly, in Orthodoxy Liturgy properly refers only to the Eucharist but I normally make use of the Western usage for the sake of consistency with Western scholarship, however, in an Orthodox context I will use verbs like
liturgize, which means, to celebrate the Divine Liturgy) but were rather classed by Fr. Robert Taft, SJ, as devotions which had become liturgized. In contrast, the Akathist is a Kontakion, an ancient liturgical hymn, sung with a formal preface and closure, and the Moleben features a Canon; likewise equivalent services among most of the Oriental Orthodox do equivalent things (such as the Syriac Orthodox
Mawrbo - a recitation of the Magnificat at night).
Also we Orthodox do pray the Hail Mary, and have multiple prayer rules for it, such as the Prayer Rule of St. Seraphim of Sarov.
