Forgive me if this question is stupid.
I have been a sacristan for five months. Less than a week ago, I became the principal sacristan at one of my parish's three churches. (That doesn't actually mean much, however, as at the moment there are only two of us. :p)
This morning I had sacristan duty for two Masses celebrated by different priests. I also had vesting duty for the first of the two. According to the ordo for our archdiocese, today is the memorial of St. Agnes and the liturgical color is red. There is no indication the memorial is optional nor does the ordo show that a choice can be made between red or green vestments, ordinary time Proper or that of the memorial.
The first Mass was celebrated by our pastor. I verified with him that he would indeed be wearing red vestments, then vested him as usual and he celebrated the Mass without incident.
The second Mass was celebrated by one of our resident priests. He vests himself. When he donned a green stole, I told him I believed the liturgical color is red today. He said it was an optional memorial, but that if I wanted he would celebrate the Mass for St. Agnes. I protested that it wasn't what I wanted but that the pastor had worn red so I thought it was obligatory. He did ultimately wear red and use the Proper for the memorial, but I got the distinct feeling he resented my having intervened. :(
Should I have questioned his decision to wear green vestments, or was I right to try to assure the ordo was adhered to? I honestly thought he may have forgotten about the memorial (Father is 82 years old and struggles to recall my name even though he has seen me several times a week for nearly eight months, sometimes multiple times in the same day) and I was only trying to be helpful.
