Thank you for sharing your story, I don’t know if it is respect that is the issue so much as it is love and reassurance that is needed here.
Your wife is not a Canadian native, she moved from an Asian country I believe? To “uproot” is a big experience physically and emotionally. All of us desire stability, your wife has already ventured into the unknown may be fearful of even more uprooting.
Please do what you can when you talk to her to focus on what you have in COMMON instead of what divides you. Perhaps tell your wife that it brings you much joy that she is a good Christian woman! Tell her you are happy you are married to someone who loves Jesus! Tell her you are excited to celebrate Christmas soon, ask her to read the bible with you! If she is upset that you cannot take communion at her church say “yes that’s true” but then quickly tell her that you both love Jesus and that is what is most important rather than give her an intellectual argument. She may be seeking emotional reassurance and the protection of a husband at this point that everything will be okay, more than she is seeking intellectual evidence of your decisions.
Show her much love, tell her you are happy you married her, tell her you are glad you married a woman that loves Jesus and that your children are blessed to have her as a mother. This kind of love and support from a husband (generally, over time) will give a woman warm reassurance that she seeks in a marriage.
I know when there were huge changes in my marriage (job, moving, children, home) my fears were that our relationship would change and my husband would change towards me. If those are your wife’s fears then reading a book about Catholic doctrine won’t help, you need to show her much love and give her personal reassurance. Please be assured of my prayers for you and your marriage and family.
