I wish I was what I sound.
here is a question for you; After communion is given and you say amen, I was taught not to make the sign of the cross because it detracts from the moment and draws attention to yourself and away from God. My Dad always crosses himself and in our Church it runs about 70/30 who cross themselves after communion......any wisdom?
The Sign of the Cross is quite probably the oldest sacramental in Christendom.
It is an expression of one's faith in God's triune nature.
When one uses it as it was intended - namely, to express faith - it is never inappropriate.
Surely one of the best times to express one's faith in the mystery of the Trinity is at the exact moment when one partakes of the mystery of the Incarnation.
There is no good or canonically legitimate reason to forbid someone from making the Sign of the Cross at communion - it is a good and pious practice.
