sign of the cross

sign of the cross
Question from on 07-31-2007:
Dear Father, First thank you for answering my past questions. I am wondering why do some people make the sign of the cross and then blow into their hands? They might not be blowing, maybe kissing? I sometimes see this after reception of Holy Communion. Thank you, Debbie
Answer by Rev. Mark J. Gantley, JCL on 07-31-2007:
There is no liturgical requirement of making the sign of the cross after receiving Holy Communion, even if this is a common custom.

It is common for people in some cultures to kiss their hand/thumb after making the sign of the cross. It is not part of the official manner of making the sign of the cross.
