Hindu, Islam, Christianity, Judaism have all been around for a very long time, longer than:
Electricty, cars, modern clothes etc.
So who and why decides that something modern can't be used in the name of religious observance?
Anyway, according to a church that I have had some dealings with in the past, we are all sinners and will spend eternity in hell, so it doesn't really matter what we do!
Not being able to cook, watch television, go for a walk, buy a sunday newspaper, fly a kite were some of the rules I had to live by for a while.
Getting your hair cut if your were a female was frowned upon as was wearing 'the Trouser".
Yet, if you lived as you were supposed to, you would still go to hell.
I wonder why I don't go to church any longer?
