How does one rebut the Jehovah's Witnesses' argument that the Trinitarianism is shown to be wrong by the "separateness" of the Father, Christ, and the Holy Spirit at the baptism of Jesus?
"Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit" Mt 28:19
"name" is singular. Thus three separate persons in one God.

and our Lord Jesus Christ,
direct(singular) our way to you.
2Thess 2:16,17 "Now may
our Lord Jesus Christ Himself, and our God and Father, (who has loved us and given us everlasting consolation and good hope by grace,)
comfort (singular) your hearts and
establish (singular) you in every good word and work."
Grammatically these would be incorrect since the verbs are referring a plural subject (Father and Jesus Christ). And yet the verbs are singular, treating the plural subject as a single entity while speaking of separate individuals Father and Son, which goes along with the concept of the Trinity.
But JW's have an even greater weakness, not simply denying the trinity, but in particular denying the deity of Christ. Plenty of clear evidence to the contrary to scrutinize them on that point.
