Christ appeared alive on several occasions after the cataclysmic events of that first Easter.

In this sentence McDowell frames the resurrection as a series of post-Easter appearances rather than a single, private experience. The wording “cataclysmic events of that first Easter” emphasizes the crucifixion-and-resurrection complex as a world-altering historical rupture, a common apologetic move meant to underscore that Christianity rests on public, testable claims. “Several occasions” gestures toward the New Testament tradition of multiple appearances to different individuals and groups, implying cumulative evidential weight. The line functions rhetorically to set up an argument from eyewitness testimony: repeated encounters are presented as strengthening the plausibility of Jesus’ bodily resurrection.
