Karl Barth, John Wesley, Richard Neihbur in relation to marijuana?

While none specifically wrote about marijuana (Neihbur died in 1962 and Barth died in 1968 but I have found no articles written specifically mentioning marijuana). So to find the answer, one just needs to look in depth at some of their writings and speeches that were given.

John Wesley wrote a book titled, "A Plain Account of Christian Perfection." There is a section titled, "Responsibility to Live Above Reproach." It is the responsibility of a Christian not to do anything that would be considered immoral. Wesley also wrote that it is the responsibility of a Christian not to do anything that would be harmful to the body. While some would say that marijuana use, especially for medicinal purposes, has no harmful effect, Wesley wrote against anything that distorted a persons ability to function. Thus it can be concluded that Wesley would be against the legalization of marijuana.

Karl Barth, while he was educationally trained as a pastor, he rejected his training as he saw it as a "predominant liberal theology typical of 19th-century European Protestantism." Many of the theologians of that time were writing about the human moral compass. That morality was dictated by the common good of the man. Barth rejected that morality was based upon human conditions but morality was based upon the condition of God. Since the current mode of legalization of marijuana is based upon the changing moral conditions of mankind, it can be deduced that Barth would oppose the legalization of marijuana.

Neihbur was a Christian ethicist who was one of the early relativism teachers. Not in the sense of moral relativism today, but that God doesn't change, but mankind does. Because of this, the ways in which God is apprehended are never permanent. God is always understood differently by people at different times in history and in different social locations. Niebuhr's theology shows great sensitivity to the ways in which expressions of faith differ from one religious community to another. Even through this, he was still critical of the liberal social gospel, describing its message as, "A God without wrath brought men without sin into a kingdom without judgment through the ministrations of a Christ without a cross." One of Neihbur's greatest works was "Christ and Culture." It primarily centers around a Christians response to differing world cultures. Neihbur would be the hardest one to understand. On one hand he recognizes that God is never changing and if He said it is sinful, then it is still a sin. Yet, he also recognizes that man through their own morality declares what is and isn't sinful. Thus I would speculate that Neihbur's response would be something similar to, "God declared that our bodies are the temple and that it is the responsibility of the person to keep it clean from any pollutants."

I am fairly certain that Wesly and Barth would definitely be against the legalization of marijuana and Neihbur would possibly be.
