Some of the comments on this thread, even before I went to bed last night, reminded me of an occasion when Larry Lewis spoke to the RCIA class at our parish. My husband and I, who are also both converts, were sponsors in that class.
One of the candidates, a mature man, maybe in his late 40’s, asked Larry about opposition from one’s family, and what could be done. Larry said that it hurt him and Joetta every day to know that their children felt such hostility toward the Catholic Church, and such resentment at the path their parents’ journey had taken. All he could do was suffer it, like Jesus suffered and Mary suffered.
That happens to very many converts to Catholicism. I experienced actual rejection from my Protestant friends. And it took some time for my father and mother to accept my conversion. However, in the end, both of my parents were ministered to by a priest in the last hours of their life. Deo gratias.
If I were asked to say in one word what converted my wife, I would say, my Rosary.
But beside suffering and prayer, we give witness with our own church life, reason, knowledge of the Holy Scripture, and ardor in defending the Faith from calumny.
