As to his statement that "Yah'shua clearly stated that there is only ONE G-d: YHvH. see Mark 12:29, where Peter is quoting Yah'shua." -- and that "YHvH has appeared to mankind at various times in different modes." --> I stand corrected -- XeniaST does believe in the Unity in Trinity, God the Father, Son and Holy Spirit
