It must be legible. For it is there above all for the instruction of the people, it is a theology in figures. The work must be finished.

Sacred art is in absolute dependence upon theological wisdom.
In the signs it presents to our eyes something infinitely superior to all our human art is manifested, divine Truth itself, the treasure of light that was purchased for us by the blood of Christ. It is above all for this reason, because the sovereign interests of the Faith are at stake in the matter, that the Church exercises her authority and magisterium over sacred art. There are other instances. Here is a point that merits all our attention. The Stations of the Cross which raised such violent commotion in Belgium gave birth to deep religious emotions in certain souls, nay more, brought about conversions.
