The so-called four-pointed, or Catholic, cross is also called "latin kryzh" or "rimski" (in Polish), which means - a Roman cross. The execution of the cross was introduced by the Romans and, accordingly, was considered Roman. From the 3rd century to this day, the four-pointed cross is the most used in the West.
As for the Orthodox eight-pointed cross, according to the Gospel, the crucified Christ carried the Roman four-pointed cross on his shoulders to Golgotha, and only during the execution on the cross appeared an emphasis for the feet of the crucified - a foot, because the Roman soldiers did not know until the moment of the crucifixion how much the feet of Christ will reach places. The upper cross-hair symbolizes the title, which also appeared during the execution, on which Pilate made an inscription stating the guilt of the person being executed.
According to Orthodox canons, it is this form of the cross that most corresponds to the historically reliable form - for it was on such a cross that Christ was crucified, and it was after suffering in atonement for human sins that he was resurrected on such a cross, confirming the immortality of the human soul.
