The Pretender (1987)

This 39 minute film is available with two other shorts by the Christiano brothers (and that has to be a pseudonym) on video. It's reportedly an often seen and fairly well-regarded film in some Christian circles, but its amateurism and 1980's fashions have made it an easy target for some. A guy wants a girl to be his girlfriend and she's a devout Christian, so he pretends he is too. She falls for his routine for a while, but is saved from sleeping with him and learns a valuable lesson, a lesson that seems questionable if you didn't believe it already. It isn't worth seeking out and the other two films are actually worse.
