5 On the centenary of the event which now fills your hearts with legitimate rejoicing, Pope Leo XIII of happy memory with his Letter Longinqua Oceani recalled and examined the progress that had been made by the Church in America and he accompanied his review with some admonitions and directions whose wisdom equals their paternal benevolence. 6.What Our august predecessor then so well wrote is worthy of repeated consideration. During these past fifty years the Church has not faltered in her course but has extended her influence to wider fields and increased her members. For in your country there prevails a thriving life which the grace of the Holy Spirit has brought to flower in the inner sanctuary of your hearts; the faithful throng your churches; around the Sacred Table they gather to receive the Bread of Angels, the Food of the Strong; the spiritual exercises of St. Ignatius are followed with great devotion in your closed retreats; and many heeding the Divine Voice that calls them to the ideals of a higher life receive the priesthood or embrace the religious state.
