Where does it say in Scripture that the Pharisees had "jurisdictional authority of the keys and the power to bind and loose"?
And where does it say the Pharisees received their authority via an unbroken line of succession handed down from Moses? As I pointed out, "sit in the seat of Moses" is a functional role, not a successional one; that "line" was broken after Joshua, further broken during the Exile, and the Pharisees arose as an independent sect as a result of religious-political events related to the Macabbean Revolt, not authority handed down from Moses.
