Is Tertullian recognized in he western church?
Tertullian died a Montanist heretic, so he's not "St. Tertullian". But his writings, especially during his Catholic period, are certainly a window in the early 3rd C. practice and doctrine of the Church.
Tertullian's opinions don't have relevance here, though. It's current (Latin Rite) liturgical law in the US that the people are required to kneel during the anaphora (except in unusual circumstances which wouldn't apply in a parish church), and Rome has also stated that the custom of kneeling after receiving communion is "laudably retained".
