The Bible(especially the OT) clearly says that Jesus was hanged on a cross. There is also extra-biblical evidence of it.............
Please post where in the OT connects Jesus on a cross __________________
The Christian Scriptures were Not originally written in English, so the English word cross does Not appear.
Also, Christians are to walk by faith and Not by sight (sighted things) - 2 Corinthians 5:7
This history of the 'cross' (T shape) dates back before Christian times connected to non-scriptural practices.
Not as an executional symbol but the T or Tau for the pagans as jewelry etc.
In the book History of the Christian Church says: " There was No use of the crucifix........"
So, just because KJV(etc.) uses the English word ' cross ' does Not make the executional stake or pole that Jesus died on as having a crossbar.
Roman executions were often done in groups, so for the soldiers to go to that extra work of adding a crossbeam would Not be to their advantage.
People often think only 3 people died when Jesus died but Luke 23:32 informs us there were also 'other' malefactors....(robbers) which could indicate instead of 3 but 5 at that time.
