It is a commonplace that even a so-called “private” Mass is never truly private. The steps, cruets, candles, paten, chalice, the fringe of the stole the edges of the pages and the priest’s fingertips are wreathed about with myriads of Holy Angels.
Because The Present Crisis is also driven the the demonic, the Enemy, we should be familiar with who Holy Angels are and what they do for us. They are with and around and before and above and behind us always, nowhere more so than during our sacred liturgical worship, a foretaste (or should be) of the liturgy before God’s throne and altar on high.
At my old stomping grounds, The Wanderer, there is a good piece readable online about angels and sacred liturgical worship. You should have a look.
