“Then one of the elders addressed me, saying, "Who are these, robed in white, and where have they come from?" I said to him, "Sir, you are the one that knows." Then he said to me, "These are they who have come out of the great tribulation; they have washed their robes and made them white in the blood of the Lamb.” (Revelation 7:13-14)
That reading was from Revelation 7:13-14. I was raised on that fantastical image of white robes washed in the blood of the lamb, and many others images from the book of Revelation. Revelation figured prominently in many sermons, church camps and Sunday School lessons. And it was always interpreted literally, which was terrifying.
