great suggestions, especially reading Kimberly Hahn’s testimony. Meanwhile, you are still married, your husband is still head of the family. How would you be treating him if he were going through another enthusiam? Taking up golf for the first time, getting really into birdwatching or civil war re-enactments. You would try to show an interest, listen when he wants to talk to you about it, at least go on an outing with him once or twice. Respect what he has to say, really listen instead of mentally preparing your rebuttal. Just as he has to respect your conscience. Time will tell if this is a passing thing or a real spiritual change coming in his life, either way you are his wife and must stand by him, even if you agree to disagree. I believe most Baptists are very strong on respecting the individual’s conscience, so you can cling to this.
One thing my Baptist relatives learned – never, never start praying the rosary. My sister married the son of a Baptist minister (one of the loveliest most Christian couples I have ever known) and after a family tragedy requested that I send her a rosary, and instructions on how to pray it. I sent a scriptural rosary, and advised her to recite the scripture verses if she felt funny about the Hail Mary prayer. She said she felt better going back to the prayers of her childhood. Soon her husband began praying with her, then her sister-in-law who had just lost her young husband, then one by one other family members. Now all of them are in RCIA and preparing to become Catholic. I have sent them a total of 24 rosaries to date.
