As for being confused for a priest, why not correct the person when they make the mistake of calling a deacon a priest? Or are we afraid of correcting people nowadays too?
Yes, yes we are. We live in a terrified, politically correct society where being corrected is the worst insult you can receive, and correcting someone the worst task.
I once saw what i presumed to be a priest wearing a cassock in my parish, and complimented him, saying ‘Father, this is the first time I’ve seen a parish priest in a cassock and I’m really glad you chose to wear it.’ He corrected me, saying he was actually a seminarian. I apologized for the mistake, and we had a delightful conversation. He is a very interesting man and will wake a wonderful priest some day. The point, however, is that it is
so exceedingly simple for any deacon in a dalmatic to simply say “No, I am a Deacon.” If a deacon is chosing not to wear a dalmatic out of fear of being mistaken for a priest, it seems like he’s almost afraid of having to explain his role to the people he is supposed to be preaching to gospel to.
Every Sunday is a little Easter, but every day can’t be Easter Sunday. There have always been days on the liturgical calendar that have greater or lesser solmenity. You can’t make any Mass more solemn unless some Mass or another is, in some way, less solemn. It seems reasonable to do this by way of accidentals, like the decoration of the church and how elaborate the vestments are.
I understand. Not every mass can have a full choir and an organ, with a long train of priests and altar servers. But what i meant in the context of this discussion about dalmatics, is that i can not imagine a case where one would WANT to lessen the solemnity of the mass by purposefully not wearing a dalmatic. That is just my personal taste. If some deacons and their congregations would feel uncomfortable with a dalmatic being worn during mass in a gym of whatnot, then that is their pastoral decision, and as it is perfectly legal according to the GIRM, I wont complain.
Additionally, i can understand why heat might be an issue. I live in a pretty hot area of california for half the year, and i can understand why heat would be a problem. But i think there are vestments (of all types) made of light enough materials to minimize that issue. But again, if the parish simply cant afford that extra expense, It is through no fault of their own and as long as they’re doing everything in their power to create a reverent atmosphere with the resources they have, I commend them.
(PS: This is a
great example of why you don’t like the GIRM? Really?

)
Yes, it is; it is vague and open to widely divergent interpretations, which has the potential to lead to discord and controversy. Thus, it is a great example of some of the weaknesses of the current edition of the GIRM, in my opinion.
Spiller:
I’ll say add something else. Our deeply challenged deacon used to wear dalmatics that looked indistinguishable from chasubles except when his hands were in the “orans position” (picture an NFL ref signaling a touchdown) or if he was elevating the chalice really high.
Maybe thats what the deacon i assumed was in a chasuble was wearing. If i were his pastor i would probably also ask him to stop wearing that type of vestment.
Spiller:
NB: Your questions suggest you are focused more on the uniform than the ministry. Focus on what’s important – the garb will follow…
I agree that focusing on a reverent, worshipful atmosphere will eventually manifest itself in the proper vestments. But it works the other way, too: using reverent vestments which lift the mass to greater solemnity can also foster an atmosphere of greater awe and wonder at a mass. It works both ways, and both ways must be used. I would never advocate focusing on one at the expense of the other. Some places just need some extra help with the one aspect and may be doing pretty well with the other.
