Let it be.

This sounds like a whole lot of none of your business. Honestly, the work guy sounds like a dolt and talking with him will likely only cause problems for you. Maybe his wife cheated on him. It doesn't concern you.

The guy hasn't seen his wife in 8 months, but she's 3 months pregnant, and the preacher attributes that to God's will, huh? There was a story in the news a couple months ago about a snake that gave birth without exposure to a partner? This guy's wife a snake? Preacher think this is what happened to her? Yeah, this story'd have me wanting to ask the guy all sorts of questions, too, but I wouldn't. That your friend had to drag you out of the room might also suggest that he sees the same credibility gaps. Laugh it off and see how the story plays out, but let the guy do the math on his own.

If he is going to love this child as if it's his own, I would not say a thing. The child deserves a loving father. Making him lose face, even to himself may not have have a good outcome.

Unless your pal is a true moron and/or is that brainwashed, he has figured this out for himself. If he wants to go along with the charade, let him go. There is no need for you to inject yourself into this melodrama any further. And bibs are a nice gift for a baby shower.

He knows already. If he chooses to say that the kids his then he is doing right by the child.
I got married after my 1st kid was born. At the time there was a legitimize form (LA) that I could fill in, to de-bastardize him. (No longer required under UK law) But I looked into the history of the laws in this respect. At the end of WW2, a guy could not disown any child born in wedlock. Even if he had been a POW at the time of conception. It was felt that there were so many cuckoos due to.... well there was a war on, that it would upset society too much if they all did.

If he can't work it out it's either because he's CRUSHINGLY stupid, or he doesn't WANT to work it out.

In the first case telling him would probably be pointless, in the second his reaction could be really bad - leave him in peace to enjoy his delusion.

I remember a neighbour in a small village. He had about half a dozen children. Every afternoon the principal of the catholic school would visit his wife while he was working. Small village, pubs, gossip … One day someone, probably inebriated, openly asked the guy in the presence of the other drinkers whether he knew which of his children were really his. "Nope, and I don't care as long as they all call me daddy!"

Pater est, quem nuptiae demonstrant The husband is the father by law. Just keep quiet. Perhaps the poor cuckold knows that he is not. No need to rub it in.

It's Jesus 2.0! we're all saved yay!

In a situation like this, you might want to ask yourself what you hope go accomplish by either saying something or staying silent. If the guy from Brazil is a close friend of yours, then this may be enough reason to try to advise him of the truth of the matter.

I think he is really being taken advantage of.

Good chance the other kids aren't his either and he is being used as a wallet.

By all means.... remain well clear. None of your business. Or, are you in league with the

What a sucker. If you don't tell him, eventually someone will. I feel sorry for the kid.

He won't listen, you will just upset him

Unless someone asks for your advice or opinion, the best philosophy is to mind your own business.

Say nothing.
I'm a big fan of letting very willfully stupid people suffer the consequences of their decisions.
People like him is why con-men can make a living scamming people instead of getting a real job.

Best to keep quiet. He'll figure it out.

Immaculate misconception

Why in the world would you think you should say ANYTHING about someone else's private business? You don't even know this person, and no one asked you. But please feel free to continue gossiping about your friend's friend.

Either the guy is entirely clueless or he's trying to save face. You can say something to your friend, but I don't think it's your place to say anything to the worker, as he's not a direct friend of yours. As for your friend talking to him, that would be entirely his choice.

Just keep quiet, maybe down the track suggest that he takes a class in arithmetic or how children come to be.

Hey, maybe Jesus is about to be born again! Finally! Its about time! The first thing new Jesus needs to do is come visit me! What am I thinking? How is a baby gonna visit me?

Let him be in his own ignorance/disillusion.

I don't think that you can tell him anything that he doesn't already know. He has chosen to put his head in the sand. It's sad though.

I would cut contact. If he is so mystified by religion that he cannot see reason or evidence, then I think he's too far gone. However, if he came to you for advice or for your opinion, I'd be honest. Try to get him to see and connect the dots.
