In 1972, Weiner founded a campus ministry called the "Maranatha House" at Murray State University, a few miles from Paducah.

Maranatha's members were told to work hard, get the best grades, and look as good as possible in order to rise in the economic and political ladders of success to be next to influence decision-makers.

The organization was one of the major players in the Christian right during the 1980s.

It first got involved in pro-life activism in the 1970s, and this soon spread to other conservative causes.

Maranatha Campus Ministries was a Charismatic/Pentecostal-oriented Christian ministry founded by Bob Weiner which existed from 1971 to 1990.

Its primary outreach was to college and university campuses. It was an outreach of a California-based ministry called "Global Missions." Weiner and his wife, Rose, had helped lead a large revival in Paducah earlier that year.

Many disenfranchised "60's" teens found a new expression of Christianity in the center located near Paducah Tilghman High School.

Large numbers of students from the surrounding area also began attending.

Weiner and his wife, Rose drew from a wide variety of leaders and influences all across the mainstream of the Charismatic movement including Kenneth Copeland and the Word of Faith movement, The Latter Rain Movement, Dennis Peacoke, Derek Prince, Ern Baxter and the Shepherding Movement, Paul Cain and the prophetic movement, Paul Jehle, Gary North, and other non-Charismatics who had Reconstructionist or Theonomic ideas.

Early members were discipled through weekly meetings and periodic weekend conferences which hosted top national speakers.
