Amen! I've been trying to explain this to Wansvic for the longest time now but apparently, Wansvic is thoroughly indoctrinated and appears to be unteachable.
This Oneness Pentecostal error has already been corrected numerous times. Oneness Pentecostal theology maintains that baptism must be by immersion using the formula “in Jesus name” and not the formula “in the name of the Father, the Son, and the Holy Spirit” as is found in Matthew 28:19. The phrase, "in Jesus' name," “in the name of the Lord,” is not a reference to a baptismal salvation formula but a reference to
authority. It is similar to hearing someone say, “Stop in the name of the Law!” We understand that the “name of the Law” means by the authority of the Law. It is the same with baptism
“in Jesus’ name.” To baptize in Jesus’ name is to baptize in the
authority of Jesus.
Therefore, the Oneness Pentecostal people are simply in error by demanding that baptism be done with the formula “In Jesus name.” Instead, it should be done as Jesus commanded:
“Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit,” (Matthew 28:19)
The proper way to baptize in Jesus’ name is to say, “I baptize you in the name of the Father, and of the Son, and of the Holy Spirit.”
