I intervjuet med msgr. Bux (ser her) kan man også lese hva han mener om alterkors:
… having the cross at the center of the altar is a way to bring to mind what the Mass is. I do not speak of a “miniature” cross but of a cross such as can be seen. The dimensions of the cross should be proportional to the ecclesial space. It should be brought back to the center [of the altar], aligned with the altar, and everybody must be able to see it. It should be the focal point of the faithful and of the priest, as [the former Cardinal] Joseph Ratzinger says in his Introduction to the Spirit of the Liturgy. It should be in the center, independently of the celebration, even if it is Mass “facing the people.” I insist on a cross that is clearly visible. Otherwise, what is the use of an image that cannot be sufficiently profited from? Images refer to the prototype. We all know that historically there have been those who were against the use of images, for example Epiphanius of Salamis, or even the Cistercians; however, the cult of images prevailed at Nicea II in 787, on the foundation of what Saint John Damascene said: “The image recalls the exemplar.” This is still valid for our so-called Civilization of the Image. In an era in which vision has become the favored medium of our contemporaries, it does not suffice to have a little cross that lies flat or an illegible “sketch” of a cross, but it is necessary that the cross, along with the figure of the Crucified, be clearly visible on the altar, regardless of the angle from which it is viewed.
