"I know 1 Corinthians 16:2
is considered proof respecting the first day; but when examined, I
think it proves the contrary. It says, “Upon the first day of the week,
let every one of you lay by him in store as God has prospered him,” etc.
The expression “lay by him in store,” I think plainly implies that they
were at home, rather than at meeting." T.M. Preble
