So, this has been bugging me for awhile. At the Chrism Mass, I went to get our oils and the new DRE had not ordered any. As I frantically texted him and Father, the DRE said that we had old oils on hand that he was going to use. I asked him if we were allow to do so. He said we were. I looked up quickly a Cannon Law reference that did not sound like we were able to do so.
Later the next day I apologized for sounding rude, I just was trying to make sure I got the right thing (just the small vials of oil) before I drove home. The DRE said that liturgically they were correct with the old oils and the small vials of the new.
What is correct? Can you use the old oils with the new?
