I am not one to be blasphemous but I too have always wondered why it was proper for two women to not only serve at the last supper/first mass but also to share in the event.
I am not aware of any women being at the Last Supper. I know that there has been speculation but that is all it has been no women are mentioned at all either serving or sharing
Not only that but they also were there to not only witness Jesus being taken down from the cross but also to bath and swaddle Him in clean cloth for burial.
They had not performed the burial ritual because there wasn’t time. I doubt if women could have done it on their own. They had the help of men.
Where were the men who shared in the last supper when that was being done I might ask?
And it matter because

Then who might I ask were the first witness’ to the fact that Jesus had risen from the dead?

Now the discussion is relegated to a woman’s place on the altar when instead I think it should be why are women now denied the joy of saying mass as are men?Because that is the way Jesus said to do it and His Church has no authority to do otherwise. Just as men are denied the joy of giving birth. What right do we have to tell God He is unjust
