What would he have thought?
The friend was babbling excitedly about something and Tholmai's son was skeptical, to say the least, but at his friend's insistence, he went along to see what all the fuss was about.
When they arrived at their destination, Tholmai's son saw a man (whom he had never seen before) talking about him. They were good things, but strange to hear from a complete stranger.
"How do you know me?" Tholmai's son asked.
"Before Phillip called you, I saw you under the fig tree."
Tholmai's son saw the light. "Rabbi, you are the Son of God; you are the King of Israel."
There was a smile. "You believe because I saw you under the fig tree. You will see greater things than this."
Nathaniel, son of Tholmai (Bartholomaios), indeed saw greater things, including the death and resurrection of Christ, and he would help spread tidings of these things to the world.
Today, we celebrate the Feast of St. Bartholomew, Apostle.
