Martin was ordained as a minister of the Regular Baptists in 1951, but this was revoked in 1953 owing to his remarriage. However, Martin met with the key pastor involved in this revocation and a restoration agreement was apparently reached, as Martin began marrying couples on television and continuing in public pastoral roles with the full knowledge of the Baptist denomination. His status as a minister has been the subject of much controversy but his daughter, Jill Martin Rische, has made more information available that puts much of the controversy to rest. Walter Martin served as a pastor in various churches in New York and New Jersey in the 1950s and 1960s. He also became a regular teacher of Bible study classes at Barnhouse's Church in New York City. In later years Martin would serve as a preacher and Bible teacher at Melodyland Christian Center and then at Newport Mesa Christian Center in California.
