TRUTH-- It was a single piece of wood like the bottom portion of a tree.
The Greek word translated "cross," is stauros, which means an upright pale or stake. Here is what Vines says:
Topic: Cross, Crucify<A-1,Noun,4716,stauros>
denotes, primarily, "an upright pale or stake." On such malefactors were nailed for execution. Both the noun and the verb stauroo, "to fasten to a stake or pale," are originally to be distinguished from the ecclesiastical form of a two beamed "cross." The shape of the latter had its origin in ancient Chaldea, and was used as the symbol of the god Tammuz (being in the shape of the mystic Tau, the initial of his name) in that country and in adjacent lands, including Egypt. By the middle of the 3rd cent. A.D. the churches had either departed from, or had travestied, certain doctrines of the Christian faith. In order to increase the prestige of the apostate ecclesiastical system pagans were received into the churches apart from regeneration by faith, and were permitted largely to retain their pagan signs and symbols. Hence the Tau or T, in its most frequent form, with the cross-piece lowered, was adopted to stand for the "cross" of Christ.
As for the Chi, or X, which Constantine declared he had seen in a vision leading him to champion the Christian faith, that letter was the initial of the word "Christ" and had nothing to do with "the Cross" (for xulon, "a timber beam, a tree," as used for the stauros, see under TREE). See 1 Peter 2:24.
As you can clearly see, the symbol that Christians use to represent "the Cross" did not become associated with the crucifixion until 200 some years after the eventand is in reality a pagan symbol of another god. In other words, in their/your attempt to identify yourself /themselves as Christians you, they and them are ignorantly glorifying the Chaldean god, Tammuz.
Sometimes I wonder why I even bother writing things of this nature since no one if anyone at all will be changed by what I write. The reason I continue to do it is to expose the error that is being believed and practiced by religious Christians and expose unbelievers to the real truth of what the Bible says about itself.
Furthermore, since Christ was not crucified on 2 cross-membered pieces of wood, his hands were over his head. It only took 2 nails to do the job. If anyone comes up with the 3 nails that were used you will know it is not true.
Do the the things I write about here in this blog make any difference to you?
