Rev 19:13

13 He is clothed in a garment sprinkled with blood. His name is called “The Word of God.” 

clothed with a robe dipped in blood –  we might relate this to the stain of blood described in Isa 63:3, the “lifeblood sprinkled on the garments” of the Spirit of Christ, who treads the wine press. But it seems that the Rider has only just appeared in heaven, and not yet begun His battle. The Rider is the saints, as the Body of Christ, whose “robes are washed white by the blood of the lamb,” Rev 7:14; Rev 22:14. The word “dipped” is actually baptó, with essentially the same meaning as baptismos, “to dip,” and refers to the washing away of their sins through baptism. The “martyrs” who went through the Great Tribulation were “given” white robes when they died, but these in the Sanctified Church have their robes washed white through baptism. The Sanctified Church has the evidence of the Spirit to wash away sins through baptism (John 20:22-23).

His name is the Word of God –  the Sanctified Church follows the Word of God, the Bible.
