Puerta del Rebaño  (Door of the Sheepfold) is an Anabaptist congregation in Concepción. Mission Network and Mennonite Church Canada responded to their interest in Anabaptist courses and in participation with other Anabaptist churches in the Americas. John Driver, the facilitator for some of the courses in 2003, noted that the Puerta del Rebaño church offered an exciting understanding of the social gospel, where church was experienced “not as a hierarchy, but as a community.” The church is known for its use of fine arts as a part of its witness and ministry.

In the early 1990s, Carlos Gallardo and his wife, Mónica Parada, were students in the Evangelical Theological Community where Titus Guenther and Karen Loewen Guenther taught through Mission Network’s predecessor agencies. Carlos and Mónica arrived at Puerta del Rebaño in 1997 and soon became pastors. The church had been founded by fine arts professor Carlos Salazar in 1986. The congregation was compatible with Anabaptism and a community approach, and Carlos and Mónica were prepared to teach what they had learned and work together in forming an Anabaptist community of faith.
