Many Episcopal Churches celebrate their Liturgy ad orientem and receive Holy Communion kneeling. They have no "hang-ups" about it!
The next video shows the Lutherans doing it the same way! And like many Episcopal Churches, they too offer their Liturgy "ad orientem!" They have no "hang-ups" about it or belabor a theology that opposes these traditional postures which they have kept since the earliest days of the Reformation. These are Catholic postures!
The Holy Father's desire for ad orientem Masses and kneeling for Holy Communion must be born of not only getting back in touch with our own tradition and roots, but also ecumenism. The Holy Father is the pope of ecumenism!
