Under the name 'Misión Hechos 4:12' ('Mission Acts 4:12′), eight congregations in the city of Managua and its suburbs have come together. Since 1999, the ÉAJC has agreed to provide supervision and logistical assistance to Pastor Rigoberto Membreño, founder of 'Misión Hechos 4:12'.

Since then, this work has been officially integrated into the EAJC network. Each of the congregations in Managua has its own building and is under the supervision of a local pastor.
