What is the proper way to do the cross. From what I have known, Catholics use 3 fingers(thumb, middle and index fingers) to to do cross in which they move their fingers from the forehead to the heart and from left shoulder to right shoulder. But in the case of Eastern Orthodox Christians they bring their 3 fingers from right shoulder to left shoulder(reverse of what the Catholics do)
My question is which is the correct way to do the sign of the cross? Or does it really matter what way you do the sign of the cross?
