Hi Brotherdan
1/ 1914 is derived from Bible chronology and prophecy we are allowed to use both of these and indeed are supposed to.
2/ The bible itself calls him the Angel of the covenant.
Malachi 3:1 Amplified bible
BEHOLD, I send My messenger, and he shall prepare the way before Me. And the Lord [the Messiah], Whom you seek, will suddenly come to His temple; the Messenger or Angel of the covenant, Whom you desire, behold, He shall come, says the Lord of hosts.
3/ what are Christians? and was Jesus a man?
Acts 26:28-29 (New International Version)
28 Then Agrippa said to Paul, "Do you think that in such a short time you can persuade me to be a Christian?"
29 Paul replied, "Short time or long—I pray God that not only you but all who are listening to me today may become what I am, except for these chains."
4/ They haven't made a single false prophecy as they have never claimed inspiration ever.
5/ We do not speak ancient Hebrew the bible inspired in three different languages allows for transliterated names from one language to another. Jehovah uses all of YHWH the complete name of God in written hebrew. Think about the English form of Jesus you use that bears little resemblance to the original Yeshua or yehoshuah or Iesous that are his name in different languages. You condemn from the an unbiblical preposition that God wants us all to speak Ancient hebrew or that his name only counts in that language alone (a rule you only use on Jehovah's name and apply to no other name least of all Jesus's)
6/ 144,000 is a Bible teaching and so is Jesus choosing his firstfruits to be kings and priests with him in heaven. He mediates a covenant with them that effects all mankind. But if you think Everyone will be kings and Priests in heaven over a few sheep and goats on earth that is your choice.
7/ Acts 1:8 is not about using a name but about what we preach and we do preach and witness about Jesus we just don't lop off his father and stick Jesus on his throne. Jesus said it himself.
John 17:1-3
1 After Jesus said this, he looked toward heaven and prayed: "Father,.... 3 Now this is eternal life: that they may know you, the only true God, and Jesus Christ, whom you have sent.
Jehovah our Father and Jesus are not a multiple choice. We have to witness about both as Jesus himself witnesses about his father too.
Revelation 1:5
Grace and peace to you from him who is, and who was, and who is to come, and from the seven spirits before his throne, and from Jesus Christ, who is the faithful witness
8/ The bible never calls the holy spirit a person it is always refered in neuter terms and as God's power (literally the "breath of God") john 1:1 is notable like many other proof texts for trinity in it's lack of mention of holy spirit. When jesus and his father are picture in heaven they are both together but the spirit is never pictured as a person.
9/ total lie! we have never taught that salvation is through works. We have always taught that our Faith motivates true Christians to do works.
10/ like I saids earlier It willl be a rather full heaven that makes a lie out of the promises in isaiah and Jesus's own words if everyone goes to heaven.
Matthew 5:5
Blessed are the meek, for they will inherit the earth.
