Kanji is a correct match. "、"can be removed. As for "。" it is like a period in English.

kanji+hiragana combinations　
1　我らの為に祈り給え using kanji as possible
2　我らのために祈り給え KyleGoetz recommend (maybe close to official)
3 我らのために祈りたまえ
4　われらのためにいのりたまえ　all hiragana

I tried googleing.All hiragana version 4 is not so usuall version.
There is not a big difference between 1,2 and 3. But it seems that version
3 is most used.I think you can choose from 1~3.　

I should say again,I don't know official translation.
