Whose name was to be "publicly declared" by Christians?
The Bible tells Christians to witness to Christ - not to Jehovah. Christians were never instructed to do anything in Jehovah's name.
(Acts 1:8) But you will receive power when the holy spirit comes upon you, and you will be witnesses of me in Jerusalem, in all Judea and Samaria, and to the most distant part of the earth.”
(Matthew 10:18) ....before governors and kings for my sake, for a witness....
(Mark 13:9) ...be put on the stand......for my sake, for a witness to them.
(Luke 24:48) You are to be witnesses of these things.
(Acts 1:8) ..witnesses of me in Jerusalem,.....the most distant part of the earth.”
(John 1:15) (John bore witness about him, (Jesus)
(John 5:37) And the Father who sent me has himself borne witness about me.
(John 8:18) ...bears witness about myself, and the Father..bears witness about me.”
(John 15:26, 27) ....bear witness about me; and you, in turn, are to bear witness....
(Acts 9:15, 16) But the Lord said to him: “Go! because this man is a chosen vessel to me to bear my name [Jesus] to the nations as well as to kings and the sons of Israel. For I will show him plainly how many things he must suffer for my name.”
(Acts 10:39) And we are witnesses of all the things he did.......
(Acts 10:43) To him (Jesus) all the prophets bear witness....
(Acts 13:31) .......These are now his witnesses to the people.
(Acts 22:15) because you are to be a witness for him (Jesus) to all men......
(Acts 22:20) and when the blood of Stephen your witness...
(Acts 23:11) ....witness about me in Jerusalem,.....also bear witness in Rome.”
(Acts 26:16) .....a witness .....................respecting me.
(1 Corinthians 1:6) ...the witness about the Christ has been made firm among you,
(1 Timothy 2:6, 7) ...this is what is to be witnessed to in its own due time.
(2 Timothy 1:8) ....the witness about our Lord.......
(1 John 5:9) ....this is the witness God gives, the witness.....about his Son.
(Revelation 1:9) ......bearing witness concerning Jesus.
(Revelation 12:17) ....have the work of bearing witness concerning Jesus.
(Revelation 17:6) ......and with the blood of the witnesses of Jesus.
(Revelation 19:10) ....witnessing concerning Jesus...the witness concerning Jesus...”
(Revelation 20:4) ...for the witness they gave about Jesus......
Christians were to witness for Christ. There is not one single verse which commands Christians to witness for Jehovah. Jesus was assigned to be God's witness:
(Revelation 1:5) "....Jesus Christ, “the Faithful Witness,”
(Revelation 3:14) "....the faithful and true witness.."
We are assigned to be Jesus' witnesses
