While debating heretics, early Christians used the Greek term “hypostasis” – meaning “substance” and “subsistence” – to help define their belief in the Incarnation of Jesus as one person, yet with divine and human natures.

This “hypostatic union” is not the kind of subject a comedian typically raises on a TV talk show while chatting about mortality with a Hollywood legend. Then again, Norm Macdonald – who died on Sept. 14 after a secret nine-year fight with cancer – wasn’t a typical funny man. He openly identified as a Christian, while making it clear that he didn’t consider himself a very good one.

During an episode of “Norm Macdonald Has a Show,” the former “Saturday Night Live” star asked Jane Fonda – who at one point briefly embraced evangelical Christianity – this question: “Are you a religious person?”

“I have faith,” said Fonda. The host quickly asked, “In Jesus Christ?” Hesitating, Fonda called herself “a work in progress,” saying she accepted “the historical Jesus.”

Macdonald responded: “But do you believe in the hypostatic Jesus?”

When Fonda said “no,” he added, “So, you’re not a Christian. But you believe, you believe in something.”

Standup comedian, actor and author Norm Macdonald died Sept. 14, 2021 at age 61 after a nine-year bout with cancer.

Raised vaguely Protestant in Canada, Macdonald didn’t discuss the brand-name specifics of his faith even as he wrestled with his own demons, such as habitual gambling. Yet he could be stunningly specific when addressing criticisms of Christian beliefs. As a judge on NBC’s “Last Comic Standing,” he quietly shot down a contestant who trashed the Bible before praising the Harry Potter series.
