The Rt. Rev. Jack Leo Iker was consecrated as bishop coadjutor of The Episcopal Diocese of Fort Worth on April 24, 1993, and became the third diocesan bishop on January 1, 1995.

He is no longer a bishop in the Episcopal Church. The Most Reverend Katharine Jefferts Schori, Presiding Bishop of the Episcopal Church, wrote this in a November 24, 2008 letter to the House of Bishops concerning Iker:

On November 20, 2008, the Title IV Review Committee certified to the Most Rev. Katharine Jefferts Schori, Presiding Bishop of the Episcopal Church, pursuant to the canons of the church, that the Rt. Rev. Jack Leo Iker, Bishop of Fort Worth, had abandoned the Communion of the Episcopal Church, having purported to separate his Diocese from the Church. With the consent of the three senior bishops, Presiding Bishop Katharine Jefferts Schori then inhibited Bishop Iker from exercising his pastoral ministry. In response to the presiding bishop’s inhibition, on November 24, 2008, Bishop Iker issued a public statement in which he made clear that he had chosen to leave the Episcopal Church and that he no longer wished to carry out the responsibilities of ordained ministry in the Church. Accordingly, on December 5, 2008, Bishop Katharine Jefferts Schori accepted Bishop Iker’s voluntary renunciation of his Orders in the Episcopal Church and removed and released him from ordained ministry in the Episcopal Church.

Iker was succeded by the Rt. Rev. Ted Gulick.
