It might sound correct to you but it's actually incorrect. The correct sentence will read:

I go to the church once every day.

So what's the difference between 'everyday' and 'every day'?

'Everyday' is an adjective meaning 'ordinary' or 'commonplace'. An adjective, in case you've forgotten, is a word that modifies a noun. Eg. 'everyday occurrence', 'everyday people', etc.

'Every day' is an adverbial phrase that tells us how often something takes place. An adverb is a word or phrase that modifies a verb (most of the time).

To Sum it Up

1. Use 'Everyday' if you are implying 'ordinary' or 'commonplace'.
   
   
2. Use 'Every day' if you are implying that 'something happens every day'.
