Who encouraged John Donne to become an Anglican clergyman?

As early as 1607, friends began urging John Donne to take holy orders in the Church of England, though he initially felt unworthy and continued to pursue secular employment.1

It was ultimately King James I who played a decisive role in his transition; in 1614, the King refused Donne's final attempt to secure a court position, stating he would appoint him to nothing outside the church. By this time, Donne had come to believe he had a religious vocation and subsequently agreed to be ordained as a deacon and priest in 1615.1
