The first thing I’d like to point out is that during Jesus’ time, the Israelites largely relied on the Pharisees, and ultimately the High Priest, as their authority in matters of faith. If there was disagreement, what the High Priest said was considered final. In that sense, this structure seems more reflective of the Catholic magisterial framework than of the Protestant doctrine of Sola Scriptura.
Yes, but what did these priests and Pharisees do to our Lord and Savior?
Mat 20:18 “Behold, we are going up to Jerusalem, and the Son of Man will be betrayed to the chief priests and to the scribes;
and they will condemn Him to death,
Mat 26:14 Then one of the twelve, called Judas Iscariot, went to the chief priests
Mat 26:59 Now the chief priests, the elders, and all the council
sought false testimony against Jesus to put Him to death,
Mat 27:1 When morning came,
all the chief priests and elders of the people plotted against Jesus to put Him to death.
Jesus condemned them for teaching people their own rules and traditions over keeping the commandments of God, He went on to say they were the spiritual blind leading them and the people who followed them into a ditch
Mat 15:1 Then the scribes and Pharisees who were from Jerusalem came to Jesus, saying, 2 “Why do Your disciples transgress the tradition of the elders? For they do not wash their hands when they eat bread.”
3 He answered and said to them,
“Why do you also transgress the commandment of God because of your tradition? 4 For God commanded, saying, ‘Honor your father and your mother’; Exo 20:12 and, ‘He who curses father or mother, let him be put to death.’ 5 But you say, ‘Whoever says to his father or mother, “Whatever profit you might have received from me
is a gift
to God”— 6 then he need not honor his father [
a]or mother.’
Thus you have made the [b]commandment of God of no effect by your tradition. 7
Hypocrites! Well did Isaiah prophesy about you, saying:
8
‘These people draw near to Me with their mouth,
And honor Me with their lips,
But their heart is far from Me.
9 And in vain they worship Me,
Teaching as doctrines the commandments of men.’ ”
10 When He had called the multitude to
Himself, He said to them, “Hear and understand: 11 Not what goes into the mouth defiles a man; but what comes out of the mouth, this defiles a man.”
12 Then His disciples came and said to Him, “
Do You know that the Pharisees were offended when they heard this saying?”
13 But He answered and said, “Every plant which My heavenly Father has not planted will be uprooted. 14 Let them alone.
They are blind leaders of the blind. And if the blind leads the blind, both will fall into a ditch.”
Thankfully Jesus is our High Priest and we no longer need a mediator, because we can go directly to Jesus, only He can cleanse us of all sin and unrighteousness. So when you say" it seems more reflective of the Catholic magisterial framework" it doesn't seem as a good thing according to the testimony of Jesus.
