The Resurrection: Refutation of the Myth Theory

Peter Kreeft and Ronald K. Tacelli in Chapter 8 of their Handbook of Christian Apologetics (1994) give six arguments against the theory that the Resurrection account was a myth created by the Apostles. The second is that there was insufficient time for such a myth to develop, citing Julius Muller's The Theory of Myths in Its Application to the Gospel History Examined and Confuted (1844).

Muller challenged his nineteenth-century contemporaries to produce a single example anywhere in history of a great myth or legend arising around a historical figure and being generally believed within thirty years after that figure's death. No one has ever answered him. (p. 191)

If the Pope Pius XII of Rolf Hochhuth's The Deputy (1964) is a myth, then the test of Muller's argument would be if that myth was generally believed by 1988.
