From a reader:
In the OF some Priest’s will bless those who present themselves in the
Communion line with their arms crossed. (Although I am doubtful to the legality of this) So can a Priest who is celebrating the EF bless those who present themselves with their arms crossed?
If it shouldn’t be done in the Ordinary Form, because it is out of place at Communion time to give blessings, why would it be okay to do it during the Extraordinary Form?
No, this should not be done in the Extraordinary Form either. But keep reading.
I encourage you to use the links I post in answers to the same questions about blessings at Communion time. Here is a handy link to an article about blessings at Communion time. That article directly addresses the issue of EMHCs and blessings, but it also covers the issue of whether or not blessings should be given at all. It provides an answer from the Congregation for Divine Worship in Rome that, no, blessings should not be given at all at that point during Mass. Communion time is for communion. There is a blessing at the end of Mass.
This is not one of those hills I think priests should get ready to die on. There are a lot of things we have to clean up in our liturgical worship that are more pressing. However, just because there are other and more serious abuses that trouble our worship (e.g., the improper employment of EMHCs), that doesn’t mean that we can just let this slide. We should start working against this practice slowly but surely.
