An old Baptist showed up at my door recently with his young grandson, Malachi. I spoke to them both and the old man gave me a bible tract. I gave it back and said I would not be going to church. Even now thinking on that boy's name, why did they name him that? Why not Nebuchadnezzar or something?

Good luck with that, hope it all remains civil for you.

Many very common names are derived from religion. My name [Dorothy] means " Gift from God". There are hundreds of others commonly used here in New England (which has a very long religious history) . No one here assumes extreme religious behavior based on that. At least I would not. I am an atheist, not an anti-religious person. I have had friends who are nuns. I do not hate people who are religious, but I hate it when someone tries to convert me. If I met those people I would ask them about the Philippines because I have never been and I like to learn about other peoples experiences and cultures. THe only think that would turn me off is if they tried to convert me.

I doubt they’ll be visiting for very long.

By very religious I assume they attend church regularly. Local Church's is all about community, seeking out like minded people so I dare say that is why they are considered "devout" in gossip circles. They attend for social interactions more than anything else. Whatever takes their fancy, freedom of belief etc. Hopefully it is not shoved down their kids throats.
Sound like a nice couple. You may be conned into babysitting duties.

I am almost glad the UK also has religious nut jobs. In the USA I am positive that child would be teased due to the ignorance of most of the population.

When remoceling our home we found a contractor. He had a very unusual name (have to look at the contract to get it) and we asked him about this. He said his parents were into giving their children obscure names from the bible. I looked up names from the bible and there are hundreds. He said to just call him Scheck. He was not religious and was a great contractor.

You should dress up as a Jehovah, and go knocking!!!
