Esther Ku’s Tik Tok Series: A Funny and Chilling Glimpse of Life in a Cult

Comedian Esther Ku, known for her appearances on shows like MTV’s “Girl Code,” “Last Comic Standing,” and “The Jack and Triumph Show,” has embarked on an extraordinary journey through her 43-part TikTok series titled “I Grew Up In A Cult.” In this captivating series, Esther Ku takes her viewers on a rollercoaster ride through her childhood within the evangelical Christian church known as the University Bible Fellowship (UBF).

With humor as her ally, she exposes the behind the scenes of a Korean evangelical ministry that targets American college students.

Missionary Roots

Esther Ku’s parents were missionaries from South Korea, who brought their devout faith and fervor for evangelism to North America. In the working class town of River Grove, Illinois, they pioneered the UBF chapter at Triton Community College.

This set the stage for Ku’s unusual upbringing within UBF. A Korean missionary named Samuel Lee and an American missionary named Sarah Berry from Mississippi started UBF in the seventies. Together they brought their version of the gospel to Chicago because they thought Americans had become too materialistic.

The Bizarre World of UBF

The heart of Esther Ku’s Tik Tok series lies in her depiction of the strange practices within the University Bible Fellowship. The cult used love-bombing techniques to draw in recruits, a tactic that involved overwhelming newcomers with affection and attention to create a sense of belonging. Esther shares anecdotes about the extent to which members went to make newcomers feel cherished and special.

The cult’s isolation techniques are another key aspect of her narrative. Members were encouraged to cut ties with friends and family outside the group, leaving them trapped within a tightly controlled environment. Esther’s humorous yet poignant storytelling brings these extraordinary circumstances to life.

Weddings on October 8th with Popeye’s Meals

One of the most peculiar elements of Esther Ku’s story is the recurring theme of arranged marriages within UBF. On October 8th, the birthday of the cult’s leader, Samuel Lee, multiple couples would get married, resulting in everyone sharing the same wedding anniversary.

As a cherry on top, the wedding receptions would consistently feature Popeye’s meals, adding an absurd twist to the cult’s traditions. Ku recounts how she was groomed for an arranged marriage by constantly serving others. Couples were often given a week’s notice of whom they would marry.
