In addition to what CM says above , about the testimony from Thomas that more than one nail was used in Jesus’ hands, there is this: **
Matthew 27:37** And above His head they put the charge against Him which read “This is Jesus the King of the Jews”.
**Note - **Here it says that the sign that was nailed above Jesus was nailed “above his head”. But yet, illustrations showing Jesus being put to death on a stake show the sign above his hands. Isn’t the above statement in Matthew more in line with his hands being outstretched, as on a cross?
So, there are two places from scripture that suggest that Jesus died on a cross, rather than on a stake with both hands nailed together above his head w/one nail, as WT literature shows.
Here’s another thing. The WT has had favorable articles about Jerome (circa AD 340 - 420) and even includes references to the Vulgate in the Reference Edition to the New World Translation. Well, when Jerome translated the Greek “stauros” into Latin he used the Latin word “crux”. Doesn’t that count for something?
