The only belief and practice that makes us One is our belief that – Jesus is Lord – and our response of obedience to Him. Those that gather are followers of Jesus. It’s not about your specific theology, views of the second coming or regard for special days etc. Those that are following Jesus and seeking to obey all that he has commanded are brothers and sisters in Christ and answerable to Him alone.
