Been rereading the thread Signum Crucis, Left or Right? (on forums – Catholic Living – Spirituality). Majority view is that it is not prohibited.
Don’t know about other lefties but for me the natural way to make the sign of the cross would be to use my left hand and touch my right shoulder first, then the left.
Thought this section might reach a wider audience for my question which is whether the mythical “average Western Catholic person in the pew or priest” would be upset if they noticed this (probably wouldn’t if they were participating fully but they might if they are like me and notice deviations to a usual pattern).
Ever seen a priest do this?
