During the trial of Jesus before the Sanhedrin:
John 18:19 [NIV] ~ Meanwhile, the high priest questioned Jesus about his disciples and his teaching. 20 “I have spoken openly to the world,” Jesus replied. “I always taught in synagogues or at the temple, where all the Jews come together. I said nothing in secret. 21 Why question me? Ask those who heard me. Surely they know what I said.”
The word for "secret" here is κρυπτῷ, from Strong's 2927, usage:
hidden, secret; as subst: the hidden (secret) things (parts), the inward nature (character) (see here)
Clearly Jesus did teach often in the synagogue and in the temple, public places. But at first glance it seems that Jesus did teach in more private (secretive?) ways as well, such as:
- The Mount of Transfiguration
- The lengthy discourse to His closest associates (just completed) from John chapters 13-17
- Private instruction to the apostles on other occasions (e.g. when they ask Him to explain a sermon)
- The layered meanings of parables, as discussed in this related question: In John 18:20 is Jesus' defense disingenuous?
What is meant here by secret? Is Jesus saying:
- He never taught in private settings? OR
- His teachings in private were the same as those in public? OR
- His meaning (regardless of setting) was plain?
