He was born in York, according to the Worthies of Thomas Fuller. Fuller also says he gained the nickname “green-head” when a young preacher at Paul's Cross, attacking inequality. He preached against the Lord Mayor, too, in 1603, when he was a lecturer at St Augustine Watling Street in London.
He was a scholar of St John's College, Cambridge in 1587, and graduated M.A. there in 1594. He studied with William Whitaker, and became a friend of Thomas Gataker. He was briefly a fellow of Sidney Sussex College.
At All Hallows, he was the young John Milton's parish priest, and may have had a say in choosing his teachers. Thomas Young may have been recommended by Stock, or Gataker. Later Stock may have had a hand in choosing Milton's replacement college tutor Nathaniel Tovey.
