Shepherd had a number of views that were criticized as being contrary to the Westminster Standards, and this led him to be dismissed from his post at Westminster. Firstly, Shepherd argued that evangelism should be carried out with covenant in mind rather than election, which will lead the evangelist to say to people, "Christ died to save you." This was criticized as being a denial of limited atonement. Secondly, Shepherd spoke of Christians being justified by "obedient faith," a phrase that was criticized as denying justification by faith alone. Jelle Faber, Principal of the Canadian Reformed Theological Seminary, compared Shepherd's dismissal to that of Klaas Schilder, and noted that Shepherd was in agreement with Francis Turretin. Faber also wrote at the time that Westminster had "lost an eminent Reformed dogmatician."
Shepherd's views were also controversial in the Orthodox Presbyterian Church, the denomination in which he was a minister. Shepherd left the OPC and became a minister in the Christian Reformed Church in North America.
