When Jesus' followers started to preach the gospel, they congregated in homes or open spaces because they didn't have temples. Their example shows that wherever we are, it is possible to take the true concept of Church that Christ Jesus left us: a church based on revelation.
His church, where the most beautiful concepts of Christianity were declared, was often in the open air, as when he gave his Sermon on the Mount. This church didn't have walls or curtains. In it Jesus sometimes spoke to thousands. He didn't need electronic amplification to be heard. There the Christ was revealed to human consciousness, bringing the balm of healing to the world.
Christ Jesus revealed his mission very clearly when he asked his disciples who they thought he was. After others had given answers, Simon Peter said, "Thou art the Christ, the Son of the living God." Then the Master, hearing the right answer, said to him, "And I say also unto thee, That thou art Peter, and upon this rock I will build my church."Matt. 16:16, 18.
