is one good source to start with.
But it’s also good to look at the arguments against the Chair of Moses being a prefiguration of the Chair of Peter, so that you know what to preemptively address.
Like, for example, this one.
So, it’s addressed in the New Testament:
Then Jesus spoke to the crowds and to his disciples, saying, “The scribes and the Pharisees have taken their seat on the chair of Moses. Therefore, do and observe all things whatsoever they tell you, but do not follow their example. For they preach but they do not practice. (Matthew 23:1-3)
So basically, what’s happening? He’s recognizing their authority, but he’s also pointing out their flaws. He’s not saying, “They’re sitting there wrongly,” but rather, “They’re in a position of authority, so do what they tell you to do, but they’re not good role models, so don’t copy their example.”
If you remember his criticism—
Then some Pharisees and teachers of the law came to Jesus from Jerusalem and asked, “Why do your disciples break the tradition of the elders? They don’t wash their hands before they eat!”
Jesus replied, “And why do you break the command of God for the sake of your tradition? For God said, ‘Honor your father and mother’ and ‘Anyone who curses their father or mother is to be put to death.’ But you say that if anyone declares that what might have been used to help their father or mother is ‘devoted to God,’ they are not to ‘honor their father or mother’ with it. Thus you nullify the word of God for the sake of your tradition. You hypocrites! Isaiah was right when he prophesied about you:
“‘These people honor me with their lips,
but their hearts are far from me.
They worship me in vain;
their teachings are merely human rules.’
Jesus called the crowd to him and said, “Listen and understand. What goes into someone’s mouth does not defile them, but what comes out of their mouth, that is what defiles them.”
So that ties into what we say about the Church and the Pope— the Pope has the authority to change Discipline, but the Pope doesn’t have the authority to change Dogma. So what the Pharisees/teachers/etc were doing were saying, “Hey, you’re supposed to honor your father and your mother. But if you make a gift to the Temple with the money that your parents were going to need in their old age-- well, that’s okay, because now it’s sacred money put to God’s work. So that’s cool.” And Jesus is saying, “No, no, and no.”
