FTBA is a trust established by the late Brother Narayana Paul, encompassing a group of assemblies located in the Srikakulam hills of Andhra Pradesh. The trust was created to provide legal support and preserve the unity of these remote assemblies.

Comprised entirely of members from local assemblies, the trust aims to maintain the autonomy of each assembly while fostering unity among them. Currently, 96 assemblies are in fellowship with FTBA, which offers legal protection to these otherwise unregistered local assemblies through a single registered entity.

FTBA operates for the assemblies, by the assemblies, and to the assemblies.
