The Heart of Jesus was the focus of Father Arnold’s ardent apostolic love, and from this same focus emanated his spirit of unlimited sacrifice, his inflexible resolution in all he undertook and endured in the service of God’s glory and his neighbor’s salvation. This love was a great grace for him when he was a young priest; it was his mission school.

In the Sacred Heart, he had the Divine Word clothed in palpable human flesh, God Himself in a distinct physical nature. Here was the means he would employ to make clear to others the divine truths he so vividly realized in his own soul; here was the channel of expression for his own theological reflections.

In Arnold’s enlightened eyes, the Sacred Heart was the most beautiful temple of God among men, the most glorious habitation of the triune God among us, the richest and purest example of divine adoption on earth, and the overflowing reservoir of grace and of the gifts of the Holy Ghost.
