 He was ordained a Redemptorist Priest three years later.The Redemptorists presented week-long missions so that regular parish members and especially the poor could receive the religious instructions given by these traveling preachers.Father Baker worked closely with Father Isaac Hecker on his missions and so after Hecker’s expulsion from the Redemptorists and subsequent permission to found the Missionary Society of St. Paul the Apostle, granted by Pope Pius IX, Baker joined fellow missionaries Isaac Hecker, Augustine Hewit, Clarence Walworth, and George Deshon in leaving the Redemptorists to found the new society.
