What is the narrator point of view in Milton's poem, On the Morning of Christ’s Nativity?

This poem has a somewhat curious use of perspective. Technically, it is in the first person, which is one of the most familiar perspectives in the English language, and very popular for poetry. However, the first person singular is what readers are likely used to seeing in poetry. This poem makes use of the first person plural, with words like “we” and “our” to identify that the perspective spoken from is part of a broader collective.
