Virginia City welcomes new preacher Paul Watson (Glenn Corbett), a former gunslinger who'd "seen the light" five years earlier. But Watson's new lifestyle-and indeed, his life itself-is threatened by the arrival of Cliff Rexford (Michael Witney), who has not quite forgiven Paul for killing Cliff's brother. Sue Randall, best known as "Miss Landers" on Leave It to Beaver, makes another of her many Bonanza appearances as Paul's wife Sue. The teleplay by Thomas Thompson and Robert L. Goodwin manages to make a passing but pivotal reference to Adam Cartwright, who'd been written out of Bonanza when Pernell Roberts left the series during its eighth season. "Mighty is the Word" originally aired on November 7, 1965. ~ Hal Erickson, Rovi
