Again, Jesus “protested” against the “church” that the Godhead had established through His covenant with Abraham, and further clarified through the Law given to Moses, decrying how it had become corrupted.
He called people to repentance and faith in Him, rather than adherence to a corrupted system of priests and “sacraments.”
In that sense, Jesus was clearly Protestant, generally a friend of sinners, and generally opposed to the mess that had become of the “official” church He had established millennia earlier.
Let me ask you: Did Jesus establish relationship directly with people, or was relationship with Christ only available through the age-old “church” and its priests and adherence to its customs?
Let me know if you get an answer.
