Typical watchtower twisting of the facts. Same as they have always been. I forget which booklet that I read it in, but something along the lines of..
Christ died on a stake because Stauros means a stake or pole in classical Greek.
The issue is that the NT is not written in classical Greek Classical. Classical Greek was not spoken for several hundred years before Christ.
The NT was written in Koine Greek and in that dialect, Stauros means both a pole or an intersecting poles [one a top the other] like a cross.
Also, Christianity was spread orally for centuries before the scriptures were confirmed. Are you going to believe that everyone telling of the Lords crucifixion was in error?
Just asking
