I have been a long time lurker on these forums and would like some advice.
I don't see a single common question in your post, which is fine, so my answer is a ramble of responses.
I grew up Catholic not by choice but Mom made us kids go. I went through the whole process and after my confirmation at age 15 (I'm 35 now) I simply stop going to church. Now 20 years later married for 11 years been together for 13 to a non-church goer, and with 2 beautiful girls I'm considering going back. I have been dabbling little by little by going to Mass with our very close neighbors over the last year taking my children while my wife stays home. I even went by myself once, so I'm on the verge to just continue going.
One main reason I would like to attend church again is for my daughters. I feel as if this will give them a foundation on life besides from what I can teach them. I'm also going for myself to feel refreshed and repent my sins that I have done and ask for forgiveness.
This is a pet peeve of mine. I don't think you are falling into this trap. Please don't rely the church to set your daughters foundations. That is your job. The church can help. You are the parent.
I dislike parents who think their work is done when they drop their kids at the Sunday School (or whatever the church calls it). Firstly it is only about 1 hour per week, you have them for far more time. Secondly you should be interested and ask them what they learnt.
I volunteered as a Sunday School helper. Most of the teachers where woman, so they appreciated a male to keep the boys in line. As a helper they didn't expect me to do much. Given it was Sunday School, there was little formality or rules to follow. Helping is an easy introduction to church.
Some other parents would sit in on Sunday School, just to observers.
I am worried about my wife though. She grew up not going to church and when her mom passed away 12 years ago at the young age of 44 she lost faith in God. It's also interesting to me that my wife lived a very permiscous lifestyle without having church involved in her life. (I was crazy myself with church so how can I judge )
After 12 years she may have changed.
Talk to her.
She is your wife, so is probably willing to step out of her comfort zone for you, if asked nicely.
Previous lifestyle is irrelevant. We are all sinners.
I also considered leaving Catholic and trying nondenominational, but I feel my roots keep me practicing Catholicism.
Given your Catholic past that seems a good place to start. Maybe investigate other denominations. And ask your wife what she might like. Even if she didn't go church, maybe she has some influence that she would like to investigate.
On a side note. My friends family and my girls and I attended church this weekend (wife home), but said she would go this weekend.
Anyone know an easy way introduced the Catholic religion to my family. I myself find it confusing at times which is one reason I stopped going at an early age.
Ask your neighbours. This is a good test of the church too. If they have been going for years but can't explain the church then maybe you also wont learn and your daughters wont have any foundation set.
Ask the church. Typically churches give introductory classes.
Google "Catholic introduction"
Also I'm not putting any pressure on my wife she doesn't have to go I'm not holding it against her I simply say I'm going to church and I ask her if she wants to go and that's it. I also do not want her to hold it against me either for going.
So ask gently. Don't pressure or order. She is your wife, so I expect she will be willing to attend at least a few times if you explain why and ask nicely.
Sorry if I'm all over the place. Early in the morning and on a phone.
Your phone is good at creating long messages. I can barely get a paragraph without a spelling mistake or some silly autocorrect error.
