How do you deal with a religious family?

[Aractus]

Here's an example for you:

At that time Joshua built an altar to the Lord, the God of Israel, on Mount Ebal, just as Moses the servant of the Lord had commanded the people of Israel, as it is written in the Book of the Law of Moses, “an altar of uncut stones, upon which no man has wielded an iron tool.” And they offered on it burnt offerings to the Lord and sacrificed peace offerings. And there, in the presence of the people of Israel, he wrote on the stones a copy of the law of Moses, which he had written. And all Israel, sojourner as well as native born, with their elders and officers and their judges, stood on opposite sides of the ark before the Levitical priests who carried the ark of the covenant of the Lord, half of them in front of Mount Gerizim and half of them in front of Mount Ebal, just as Moses the servant of the Lord had commanded at the first, to bless the people of Israel. And afterwards he read all the words of the law, the blessing and the curse, according to all that is written in the Book of the Law. There was not a word of all that Moses commanded that Joshua did not read before all the assembly of Israel, and the women, and the little ones, and the sojourners who lived among them. (Joshua 8:30-35).

That alter was discovered at Mt. Ebal and has been partially excavated in the 1980's (after being searched for for hundreds of years) by Dr. Adam Zertal, an Israeli archaeologist and a sceptic who originally believed the OT was only full of myths. There was plaster recovered with Hebrew lettering, bones consistent with animal sacrifices and the alter itself was consistent with the description given in the Talmud.
