Why Do Christians Wear The Cross?

WAS IT A CROSS IN JESUS' TIME that the authorities used to nail outlaws on?or was it done simply by tree hanging?

Peter and Paul use the word XY'LON to refer to the torture instrument upon which the crucifixion took place, and this argues that it was an UPRIGHT STAKE WITHOUT A CROSSBEAM, for that is what XY'LON in this special sense means. (Acts 5:30; 10:39; 13:29; Galatians 3:13; I Peter 2:24) At Ezra 6:11 we find XY'LON in the Greek Septuagint (I Esdras 6:31), and there it is spoken of as a BEAM on which the violator of law was to be hanged, the same as in:*Acts 13:29 "And when they had fulfilled all that was written of him ,they took him down from the TREE ,and laid him in a sepulchre"*Galatians 3:13 "Christ hath redeemed us from the curse of the law ,being made a curse for us : for it is written, Cursed is every one that hangeth on a TREE"*I Peter 2:24 " Who his own self bare our sins in his own body on the TREE that we being dead to sins should live unto righteousness : by whose stripes ye were healed "*Luke 23:39;"And one of the malefactors which were hanged railed on him saying ;If thou be Christ save thyself and us "*Acts 5:30; "The God of our fathers raised up Jesus whom ye slew and hanged on a TREE"*Acts 10:39."and we are witnesses of all things which he did both in the land of the Jews and in Jerusalem whom they slew and hanged on a TREE"

TREE HANGING IN Genesis & DEUTERONOMY IS A FORM OF CRUCIFIXION *Genesis 40:19 " within yet three days shall Pharaoh lift up thy head from off thee, and shall hang thee on a tree; and the birds shall eat thy flesh from off thee."
*Deuteronomy 21:23 his body shall not remain all night upon the tree, but thou shalt surely bury him the same day; for he that is hanged is a reproach unto God; that thou defile not thy land which the LORD thy God giveth thee for an inheritance.
BTW : Deut 21:23 was one of the reasons why Jews rejected the one they thought to be Jesus .


So should Christians start wearing a " Tree " instead of the "Cross" that never was?
