Legend has it that St. Dominic and St. Francis both had similar dreams that they met each other on the street. The very next day, their dreams became real. They met and immediate embraced each other. That is why we Lay Dominicans refer to St. Francis as our Father, too. We pray for our Father Francis, today.
But whenever I think of St. Dominic and St. Francis, I don't think our our saintly fathers. No, not at all. There's only one image that comes to mind, and that's Sister Ruth and Sister Kathleen. O.P. and O.S. F.
