its invalidity on the basis of a scriptural text or consensus. As for the proof you mentioned for the impossibility of an infinite extension, it has already been discussed. Moreover, those arguments do not apply here as they did there.
As for the first argument—the impossibility of alignment both occurring and not occurring when an infinite extension is assumed to align with a finite one—in addition to what has already been said about it, if it is finite in some directions, alignment can be supposed in such a direction. The upper point would then come into alignment from below that direction before the lower point would. But this occurs only if something is assumed to come into alignment from the direction in which there is no limit.
As for the third argument—that His essence would necessarily intermingle with filth—this does not follow if He is said to be finite on the side facing creation but not on the other side. In that case, He would not intermingle with them. Thus, this argument plainly fails here.
As for the impossibility of establishing a proof that the world is finite, this has already been discussed. Moreover, in its continued existence, the world is finite with respect to its beginning but infinite with respect to its end. It therefore has finitude in one respect but not another. This, however, is not finitude in direction, magnitude, or extension.
