Pictures or tableaux of the various Stations are not necessary. It is to the cross placed over them that the indulgence is attached. These crosses must be of wood; no other material will do. If only painted on the wall the erection is null (Cong. Ind., 1837, 1838, 1845);
If, for restoring the church, for placing them in a more convenient position, or for any other reasonable cause, the crosses are moved, this may be done without the indulgence being lost (1845). If any of the crosses, for some reason, have to be replaced, no fresh blessing is required, unless more than half of them are so replaced (1839).
There should if possible be a separate meditation on each of the fourteen incidents of the Via Crucis, not a general meditation on the Passion nor on other incidents not included in the Stations. No particular prayers are ordered;
