What did he tell them to do with the sword? Execute people?
Then why did God wait for Peter to give the sign? Hint: it might have something to do with Christ giving the authority to Peter on earth.
He gave the authority to all the Apostles (Mat 18:18). In Mat 16 he promised he would give it to him. In Acts 5:12 it says the signs were happening among all the Apostles, not just Peter. Anyway, there is no evidence that Peter was killing people for lying with this new authority .
Anyway, Acts 5:1-11 is an anecdote used for teaching and not necessarily that really happened any more than the talking donkeys in the Old Testament.
Wow. Sure you're not Protestant? Your editing of Scripture reminds me quite a bit of Luther.
