Regardless of the technical correctness…others will need to address this…
- I’m sure that the priest is well aware of your status among the faithful so mentioning it would IMHO be inappropriate.
- Why should it cause you trouble to be obedient to one who is placed in charge over you?.
You say that the priest is an older man. Is he infirm in some way?
My suggestion would be to discuss this with him. Explain that you wish to be obedient to him and to the Church and you wonder about this apparent conflict.
Hopefully he will recognize your humility and the two of you can come to a good understanding of the matter.
