In case you are one of those wondering about the title of this blog, the following may help solve any mystery. Dominus mihi adjutor is the motto of Douai Abbey. The words are taken from verse 6 of Psalm 117 (118). 
The rough translation is “the Lord is my help”. The emphasis in the context of the psalm is on “the Lord” – he is our true help, as no one else can be.
As so often happens the Latin has a deeper nuance not conveyed by the English translation. Adjutor has the sense of help in the attainment of a particular end, the realisation of a goal, the fulfilment of a mission. Thus the Lord is the one who is our true and only help in fulfilling our vocation and reaching the end for which we were made, eternal life with Him. With God on our side, whom need we fear?
Dominus mihi adjutor; non timebo quid faciat mihi homo. Dominus mihi adjutor, et ego despiciam inimicos meos. – The Lord is my help; I will not fear what man might do to me. The Lord is my help, and so I shall look down on my foes. [Psalm 117 (118), vv.6-7]
Dominus Mihi Adjutor 
So can/does adjutor convey the sense that the Lord is our help and ‘guide’ ; a stronger sense than assistance? I have in mind that Cardinal Wolsey adopted the same motto to convey that he was guided by God.

I don’t think guidance, except by extension, is really part of the meaning of adjutor, which is more about strength and endurance. To convey the sense of being a guide, dux or rector are better, even lux.

Thank you Fr Hugh. That is very helpful and I will amend my use of the term in light of your guidance 🙂

You’re welcome, but I must add the disclaimer that I am no expert Latinist! I have described my understanding. If you have lingering doubts, do please get a second opinion. 😀
