Everyone needs to remember that the JW/WT high jacked the Catholic Bible only about 150 years ago and have been trying to change it ever since. The NWT is not the Bible. Teaching hate against Catholics, but use their Bible. Forbid members from ever witnessing their services or hearing truth. Russell/JW/WT are followers of Arius. He was kicked out of the "Bible committee" of Catholic Bishops (Council of Nicaea) that assembled the New Testament as we know it. - Arius ideas and works were ordered to be completely burned and he was exiled. NONE of his teaching were allowed into the Bible. The JW/WT teaches from the Catholic Bible ... they hate.
Cross/pole doesn't really matter. Event did. What I always remember was that Jesus was said to have been ordered to carry his own cross to the hill - marched through town. Fact is that it would have been impossible, in his condition, to carry a full cross. What he was carrying, marched through town, was the cross-beam to form the cross. The humiliation was to carry his own cross beam to be hung on.
