By Fr. Donald Calloway, MIC, Catholic Exchange - “Why not create a list of wonders that describes some of the many fruits from one of the most loved devotional practices in Catholicism — the rosary? It would make for a fascinating book!”.. As I continued to ponder this question, I asked myself, “How many wonders does the rosary actually have? Seven? 10? 100?” In all honesty, the number is probably infinite. Yet, after much prayer and research, I discerned that 10 was a good number to focus on.
