Jesus left a viable Church so we would all have a definitive place to turn to to ask questions regarding faith and morals.
Jesus knew that every generation would have moral issues to wrestle, Jesus knew without a identifying a magisterium, then clergy would be free to their own thoughts, ideas, etc.
This would lead to array of different beliefs (which is common among Protestantism today). However, Jesus was all about Truth. So He wanted everyone to be able to know 100% what the true faith was. The only way to do that was to establish a visible Church. The Bible (which He didn’t leave us) would not be enough, because the scriptures are open to interpretation. However, as the Ethiopian eunuch said to St. Philip in regards to understanding the Scriptures, “How can I understand unless I have a teacher to teach me?”
The Jews had a visible hierarchy. That was never Christ’s objection to them. His issue was that they were not faithful to God’s will.
God bless
