Wow: I type faster than I thought. I’ve not got Menzies Rayner’s 1839 thoughts on baptism online, and fixed a link that makes it possible to read L. F. W. Andrews antebellum thoughts again.
See all public theological docuements at Universalistchurch.net here; there’s a special section for baptism resources.
Go here if you want to see Rayner’s document in particular.
He has some interesing thoughts, but I don’t share his conclusions.
