Mission Review has spoken to several former students from religious free schools who have experiences from their school days that are difficult to carry even into adulthood.

See the series: "School for God's sake" - SVT Play

One of them is 29-year-old Stefan, who left the religious free school Kristna skolan in Stockholm 14 years ago.

- The biggest thing I took with me from that school was a feeling of imperfection, a feeling of sin.

A feeling that I am doing wrong, that I am wrong.

Hear him tell about the words from his teacher that weighed on him for many years.

Kristna skolan in Stockholm has declined to participate in the Mission review.
