My cousin claims that after ordination, a priest must directly ask a Cardinal,
“Your Eminence, do I now possess the freedom to offer the sacrifice of the Mass?”
My cousin then says the Cardinal would then confirm that he is free to say Mass.
I find this claim really odd and cannot find any literature on it at all on the web. I have never ever heard of this rule and I am curious as to why it would even be one. I always figured once a priest is ordained, he is free to say Mass without consent of a Cardinal.
