16 To Us, no less than to Our predecessors, these capital truths are clear and certain. When We took up Our office of Supreme Pontiff and saw, in full accord with Our prayers and desires, that the devotion to the Sacred Heart of Jesus had increased and was actually, so to speak, making triumphal progress among Christian peoples, We rejoiced that from it were flowing through the whole Church innumerable and salutary results. This We were pleased to point out in Our first encyclical letter.(11)
