Are they persona non grata?

Yes.

This is so hard. I'm sorry! I am going through the same thing, though not the exact same circuмstances. And it did cause WWIII in my family. I'd like to tell you that once you get it over with and tell them things will get easier. This was not the case for me. I love my family, and I was very close to them growing up. They tell me that my religion has broken up our family. It's been one of the largest trials of my life. They are disgusted with my husband and I.

It's important that you do not give them consent for what they are doing. We talked to our priest to figure out exactly what that looked like, and his advice was very hard to swallow. I suggest getting guidance from your priest.

There is always a silver lining. It's great penance. It will bring you closer to Our Lord if you allow it to. And, if you stick to it, it'll give you thicker skin about this type of thing.

ABP Fulton Sheen once said something along these lines, "Going along with the world is as easy as falling off a log." In other words, the easiest thing for you would be to go along with it like everyone else. There is great reward at the end of the race. Our comfort must be in the thought of heaven. As Catholics we've got to get used to being spurned- it's only going to get worse. And if we want to strive to be especially saintly, we will wish to be spurned. Personally I am not there yet.

A friend of mine grew up in a very warm Mennonite family & church.  When they decided to homeschool (instead of using the Mennonite private school) they were basically shunned. She said that was harder on her than when she lost her two sons.

I know all about this. Since I reverted to Catholicism, all my relationships crumbled. Including the one with my husband. They all blame it in my religion. Accuse me of being a religious fanatic, nutjob, etc. I'm an only child coming from a completely broken family so I only had my mom but I had to almost end that relationship for the good of my soul. I feel completely alone in the world and against the world.

It has been a very hard cross for me lasting for years, despairing, but I am at the point now where I no longer care. I have cut ties with just about everyone, except my husband, who still is not a Catholic and probably will never be. I would leave if I could. These people do not have the Faith because they do not want to and they are simply of bad will. They are worldly and they just don't get it because they can't.

You better off cutting ties with people like that who will only bring you misery, most especially if you are raising children. Stay away from unholy people! not practicing Catholics, people living sinful lives. It does not matter if you start WWIII with them. What is this life compared to eternity?.  




 

Wow so many people silent martyrs for the Faith.  My commitment to the Truth of Catholic Tradition ruined my relationship with my family and my husband--it lead to our divorce (he's not Catholic and I converted to Tradition).  I saw my mother recently thinking she might have changed.  Sadly, no.  She still hates my beliefs and probably me too.  Thankfully my children see her errors.  We pray for them but until such time they are lost.

No, you mustn't receive your uncle and his concubine.  You might be able to see him without her but something tells me that would cause more problems than it would solve.

The world is in a sorry state.  Your children should not be exposed to sinful lifestyles among their own family.  They'll grow up thinking it's morally acceptable, and the faith is just a lofty ideal, or else they'll eventually despise you for your hypocrisy and reject Catholicism altogether.  In my own family, what started out as eight young couples in the early 50s to early 60s, all supposedly practicing Catholics, produced nine children who grew up through the 50s, 60s, and 70s.  Of those nine, five married, producing four children.  Of the four, one died in his teens, two succuмbed to drug abuse, and mental illness and are semi-institutionalized, no children.  One has remained single and is practicing the Traditional Faith.  
Of the five who married, only one married a Catholic in the Church but it was to appease the grandparents.  All "shacked-up" before marriage, and all five are divorced, two more than once.  Three are living in sin.  As for the four children, one is making the rounds of various concubines, one has chosen to turn herself into a man while retaining her lesbian lover---they're engaged---of the youngest two, one is attending high school part-time, working full-time, having moved out last year.  He could no longer stand the fighting, lying, and cheating.  The youngest child is stuck since he's 10 years old.  Thus far, there are no children from the four.  Not one was raised Catholic; only one was baptized, again, so as not to upset an older relative in whose house they were living.  The baptized child is the youth who moved out at age 16.  
Of the original 16 Catholics, four are still living. Of the four, two are long time widows; the other two are a married couple, 60 years last month.  One of the widows, (traditional), the couple, (conservative n.o.), and their single daughter, (traditional), are practicing Catholics.  The youngest of these is 56.  
This family disintegrated because the majority chose this world over Heaven. There was never a WWIII, only a few skirmishes over the years as each went his own way.
Sad, huh?
