The rest of the text, as far as I can see, is cryptic but gramatically correct

'church life' -> holy matrimony?
'Bound together' is obviously about a wife and husband; should this be corrected? (In which case 'wife' should remain the subject, not 'wife and husband'...)

Hmm... and I was thinking that this text isn't correct! I don't know what it means still but thanks very much for a partial explanation.

You're welcome! I hope there will be someone to translate it for you soon
