And to the end that it might be brought to fruition and permanence at the earliest possible moment, We have already insisted in Our Encyclical letter In Multiplicibus , that the time has come when Jerusalem and its vicinity, where the previous memorials of the Life and Death of the Divine Redeemer are preserved, should be accorded and legally guaranteed an "international" status, which in the present circumstances seems to offer the best and most satisfactory protection for these sacred monuments.
