I’m so happy that you are coming into the Catholic Church. I, too, expected significant opposition from my beloved older sister so, on advice from a wise woman, I wrote a letter to her and to my Mother (who lives with my sister). My Mother, the most nonjudgmental person on Earth, sent me a very sweet note the next week telling me she loves me and is praying for me. My sister did not disappoint. She sent me a four-page diatribe telling me how wrong wrong wrong I was to even think about being Catholic. She will never be happy about my conversion but we have come to terms after a several months long estrangement. And for that I am so grateful to God.
I say all of that to say this–why not consider writing a letter giving your reasons for converting. It would seem to be the wimpy way out (that’s what I thought at first) but they will know exactly why you are doing this and there won’t be any misunderstands about your reasons. You’re probably going to get some pretty significant opposition, too, but hang in there because you are doing the right thing.
And here’s what happened to me in respect to my sister. Every day I prayed that the Holy Spirit would soften her heart. Every day I prayed that prayer. As I was going to her home to babysit her after surgery I realized while praying the rosary on the drive up there, that it was MY heart that needed softening. I had wallowed in my hurt feelings and, quite frankly, was enjoying the wallow. So my prayer became, Please Lord, take that away from me and soften my heart. That very evening, when we were having devotions, the very words out of her mouth in prayer were the very things I had thought and said about her–she is rigid in her beliefs, she has an obsessive need to be right, she is sometimes harsh in her words to others (she had blasted our sister-in-law a few days earlier unnecessarily). When I heard those words come out of her mouth, BAM, I knew my prayers had been answered. But I had to change my own hard heart first.
God bless you on your journey HOME.
