what does making a cross on your chest mean
Sign of the cross The sign of the cross may be made by individuals upon themselves as a form of prayer and by clergy upon others or objects as an act of blessing. The gesture of blessing is certainly related to the sign of the cross, but the two gestures developed independently after some point. In Eastern Christianity, the two gestures differ significantly. Priests and deacons are allowed to bless using the right hand, while bishops may bless simultaneously with both, the left mirroring the right. While individuals may make it at any time, clergy must make it at specific times (as in liturgies), and it is customary to make it on other occasions.
