It is a small house-church cult led by Darwin that meets in someone's living room in Lake Hughes, California (a remote community near the desert about an hour north of downtown Los Angeles). In 2002, they changed the name of their sect from "God's Word Fellowship" to "a true church." The lower-case letters and the indefinite pronoun reflect a mock humility. In reality, Darwin and his flock believe they represent the true church. Though they vehemently deny this, they cannot identify a single other church or Christian leader—from the early church until today—whom they would be willing to fellowship with as brethren.
The members of GWF/atc often use the Lord's Day as an occasion to picket and disrupt other churches throughout Southern California, thus magnifying the shameful public reproach they have already brought on the name of Christ. They also like to picket large public gatherings with signs and slogans contrived to be as offensive as possible. In recent years, Fish and his minions have walked in front of the Tournament of Roses Parade carrying signs that extol God's anger and blame Jesus for the events of 11 September 2002.

The group also apparently "evangelizes" by leaving ugly graffiti here and there. Click here to see a sample.
