Just discovered fiancé didn’t receive Catholic Sacraments he said he had

Ashley, I can't talk about your FI's character, but I do know about different religions than my own tribal ones. During Colonial times right up til recently, either Catholic or Lutheran churches had missions, and it was once a forced thing to concert, later generations incorporating a little tribal religion with Christian traditions, or a little Christian with tribal. Like my parents I grew up in N NH. Old mill cities, and ones with any French Canadian people, are largely Catholic. But outside the cities or furthest north, most practicing or non-practicing Christians are Open Communion, or Open Table Churches. As are most ecumenical services, like ay a school, hospital or resort chapel, veteran's place, etc. But in marrying someone raised Catholic, I became more aware that Catholics are not open table. And I was aware more when in Army medical, as soldiers who have been injured come from all traditions. For Lutherans, Anglicans and many others that are very similar to Catholicism, as well as smaller more congregation based ones, anyone who has been baptised, whose heart is right ( think of reasons you would go to reconciliation or confession) may take communion, in any church offering it. Though a Catholic might not take communion in another church, these others will all be fone with any other Christian taking communion in their church. Though each has a process nearing adulthood for joining the church, it is not a requirement. And a lot of fallen away or intermarried Catholics will stop going to RCC and go to Anglican, particularly, so like Catholicism in many ways, but different in some interpretations of scripture, including acceptance of outsiders. ... Subject change: Many, possibly your FI, fond religion because they are troubled, without formal education until after they have joined the church. If your FI did as many do, and attended churches with a lot of outreach, including Anglican, on his way to being Catholic, he has likely gone to open communion. In some, you go to the rail to receive it from a special person. In others, a plate of wafers and a tray of wine/grape juice is brought to the end of every row, and passed down so every person in good conscience takes it, or passes it on. If a person with a mixed up family background, some observant, some not, has never beed to communion or confirmation classes, they are not taught that only those who have, may take communion. In the majority of Christian Churches in at least half the country, you may. It is not printed over the door in a Catholic Church. Of you stay over with friends, or camp, or go on vacation with non- catholics, or are in the military open services, if you listen to the sermon, then want communion, you take it.
You seem to think of his taking communion without CCD, communion or confirmation, a deception. But if he never went to those classes on a Catholic Church, how would he know he is not supposed to do it??? Talk to your priest, and he will tell you, there is no fault in the Church's eyes to those who may have picked up a little Christian teaching here, a little there, and now wants to seriously commit to Catholicism. And it is a solution to how would he know he should not have taken communion, well give him the lessons he missed, now. Talk to your priest. This church and most Christian ones favor people who have a bad past who make the effort to turn their lives around. If your FI had been attending services, and was seen to take communion, then asked someone, what can he do to become more involved, they might suggest being a lector, or active in parish activities, and not said, well first of all, did you finish CCD and communion & confirmation.If he has taken these later steps in good faith, and is trying to turn his life around in other ways, ones you know and ones you don't, is it more productive to help him out, rather than push him away for his past? You likely have a number of things to talk to your priest about.

It is awesome that you are thinking about what is best for your child first, that is so important. You are totally right--a stable household is SO important for a child, and we adults need to prioritize what is best for the children that we create and care for over our own happiness.

I would ask you, do you believe your fiance is capable of creating a stable household for your family? Stability includes parents maintaining a steady relationship status, but it also includes financial stability, a healthy marriage with low conflict, avoiding incarceration, providing an environment for learning, etc etc. You mentioned your fiance's lies about his credit score and education--do you believe he may lie in the future about finances and put your family in a precarious situation?

Happy to chat about this in a direct message, but I have seen first-hand how lying about finances can physically endanger your family, including your child.

I think the Priest may be able to help you think through this. I have heard that getting married just for a child is often grounds for an annulment later because it is impediment to a freely-chosen marriage, and it seems like the Priest may be able to talk you through that. It would be good for you to mention to him specifically that your child is a huge factor in staying in this relationship.

How has this not come up during your premarital counseling sessions? Setting aside the trust/miscommunication/memory issues, which are profound, have you spoken with your officiant? RCIA starts in the fall and doesn't conclude until Easter. That timeline won't work if he wedding is 4 months from now. Maybe if you decide you do want to go through with it, he could speed things along. In my experience, though, you'll need a pretty liberal priest to accomplish all this before your wedding date. Maybe you could have a civil ceremony and a church blessing, or perhaps a church wedding without the whole Mass. First things first, though. Decide if you really want to marry this man.

Hi there - can I ask what happened in the end?
