They are three persons (1 Jn. 5:7-8; Mt. 28:19). Two and three of these have been seen with separate bodies with the same eyes at the same time (Dan. 7:9-14; 10:5-7; Acts 7:54-59; Rev. 4:2-4; 5:1-7; 22:4-5; Mt. 3:16-17). If there are three separate persons, then all three would have to have a separate body, soul and spirit, as is true of any three persons we could use as an example.
