Bishop Brent's policy of not putting an altar against another altar and the initial and subsequent concentration of missionary work on areas inhabited by non-Christians explains why most of the members of the ECP are predominantly from tribal communities. This also explains why the ECP's work is concentrated in the northern and southern regions of the country. In like manner, it explains why it took almost four decades for this Church to produce its first Filipino clergymen and more than half-a-century to produce its first Filipino bishop, all of whom were from tribal communities. It was this Church that introduced literacy among these people and communities. It was this Church that first established schools, hospitals, clinics and roads in these oft-neglected communities. In time, the government was able to establish public schools, hospitals, and rural health centers for these communities. As a result, this Church phased out some of its schools and clinics in favor of the government providing such basic services needed by these communities.
