True churches recognize that there are other Christian churches outside of their own denomination that are rightfully Christian and that we can all believe different things on secondary doctrines, yet still all be saved. Jesus Christ Himself said that salvation is found in Him, that He is the only way to the Father (John 14:6), not membership in a specific church.
Maaaring magkakaiba ang kanilang paniniwala sa mga hindi gaanong mahahalagang doktrina, ngunit sila ay ligtas din. Sinabi mismo ng Panginoong Hesus na sa Kanya lamang matatagpuan ang kaligtasan at Siya lamang ang daan patungo sa Ama (Juan 14:6). Hindi makakamit ang kaligtasan sa pagiging miyembro ng isang partikular na iglesia.
