Is There a Rule of Thumb for Capitalisation in Christianity?

I've been writing some articles pertaining to Christian weddings just recently.  Mostly because the Christians here are allowing me to gazump their category. :)

However, I'm running into some vague areas regarding the correct capitalization of certain words.  I know that God, Jesus and Mary (Joseph too?) all have their pronouns capitalised, as do any nouns in the usual way.  But what other words?  Are there any more which don't necessarily follow standard English grammar?

For example, would I write 'scripture' or 'Scripture'?  How about 'the good book'?  Plus do saints, apostles, prophets, disciples and the like get capitalised pronouns too?

Basically a rule of thumb - if such a thing exists - would forestall me having to ask each time I encounter a potential anomaly from the general rules of England language.

Naturally I'd be very grateful if Wizzley's Christians would give my articles the once over, in order to ensure I've called it all correctly thus far.  Thanks in advance. <3

There are no religious rules, but merely grammar rules. I use a capital C for Christianity, and a capital S for Scripture. But you don't need to expect the Spanish inquisition bursting into your house to demand penance for improper capitalization. But nobody expects the Spanish Inquisition!

But I do expect the Spanish Inquisition!  Yet nobody expects them.  I'm a little concerned that I might accidentally open up some kind of black hole or vortex with this kind of behaviour.

I'll work on not expecting them.

Thanks for the clarification re capitalization.

I'm still expecting them. Mind you, when the Spanish Inquisition does turn up, I should imagine that correct grammar will be the least of my charges! :D

As Frank has said, grammar rules like capitalizing names, and God.

I personally don't capitalize the word "scripture" - maybe the SI will be after me too Jo!

The only other time I have seen capitalization that is off, is sometimes when God or Jesus is mentioned as "He", but in the Bible in certain verses.

Oh yes, I usually capitalize Bible too.

I was wrong.  NO-ONE EXPECTS THE SPANISH INQUISITION!  And now they're here.

Dustytoes, RUN!   I'll be fine, I have a secret escape ploy on the whole subject of expectations.

We never forgive.

We never forget.

Expect us.

Never expect the Spanish Inquisition.

Jo, it's just the pronouns as you've stated. When talking about saints, we don't usually capitalize pronouns.
