One reason why so many Christians today don't know the Old Testament is because their 'gospel' doesn't even need it.
Scot McKnightThe angels of the Bible terrify the humans to whom they visit; they startle and scare and even stun the humans. Why? Because in the Bible angels are colossal figures, fiery in light and, more often than not, overwhelming in their power. Angels, then, in the Bible are supernatural beings that humble us in their presence.
Scot McKnight... the Eucharist profoundly enables the grace of God to be received with all its glories and blessings.
Scot McKnightIn the Bible angels speak and humans speak back to them. This is the case with Mary in Luke 1. The angel speaks, Mary questions, and it goes back and forth. Abraham speaks with angels. So I would contend the Bible has enough evidence of angels speaking and humans speaking that speaking with an angel today would be reasonable. I've heard enough stories and read such that confirm that Christians today do speak with angels.
Scot McKnightI've never spoken with an angel, though one time I felt the awesome weight and glory of God's presence in an angel in my bedroom as I kneeled in prayer. I kept my eyes closed, good Baptist that I was at the time, so I never knew if it was an angel. (I now am reasonably confident it was.)
