I think I said earlier that you sounded as if you may be of the WWCG.

"A Higher Calling: Quest for the Kingdom of God" mentions how God called me into His Church during the days when Herbert W. Armstrong was courageously teaching the plain truth around the world, announcing the good news of the Wonderful World Tomorrow, the Kingdom of God that will soon be established with the return and reign of Christ.

The present WWCG doesn't claim them as their own doctrine any more.

Rather, God doesn't claim the WCG as His Church any more, as that apostate organization has returned to the traditional vomit of Babylon that many had escaped. It is now part of the Synagogue of Satan. God isn't associated with it in any manner, shape or form.

He did not teach the plain truth of the Bible.

Then you've never read the Bible without your traditional blinders. Try it, so help you God.

He taught that God is a family...

The Bible teaches that God is a family. Why don't you believe the Bible? Herbert W. Armstrong taught the plain truth of the Bible.

Ephes. 3:14-15
14 For this reason I bow my knees to the Father of our Lord Jesus Christ, 15 from whom the whole FAMILY in heaven and earth is named...

Don't you know what a Kingdom is but a Royal Family that rules over a specific territory, administering specific laws? Yeshua came preaching the Kingdom-Family of God that will soon administer the Law of God, the government of God, over the Earth and throughout the universe. Won't you repent and believe the good news that we can be born again into the Kingdom-Family of God at the resurrection at Christ's return?

"...that Jesus did not exist before His birth in Bethlehem"

That's a lie. Why do you repeat such nonsense?

Here is one of many examples of how Herbert W. Armstrong clearly taught that Yeshua was the Word with God in Heaven before he was divested of divine glory to become human so we could become divine:

"In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made. In him was life; and the life was the light of men (John 1:1-4)..."

"So here we find revealed originally two Personages. One is God. And with God in that prehistoric time was another Personage who also was God; one who later was begotten and born as Jesus Christ. But these two Personages were spirit, which is invisible to human eyes unless supernaturally manifested. Yet at the time described in verse one Jesus was not the Son of God and God was not his Father. "

Who and What Is God?

"...that water baptism is essential for salvation"

The Scripture says repent and be baptized. Why don't you believe the Bible?

"...that we must work to earn Heaven"

Herbert W. Armstrong believed the Bible and taught "the meek shall inherit the Earth" - just like Jesus. Why don't you believe the Bible? Why fall for the traditional lie about "going to Heaven?" Herbert W. Armstrong knows we are saved by grace alone, that we are pardoned and empowered, that Christ is to live in us as we exercise faith and works:

Ephesians 2:10
For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.

May you repent of spreading lies about God's faithful servant, Herbert W. Armstrong; repent of misrepresenting God, Jesus Christ and Christianity with your traditional Babylonian Mystery religious error; repent and believe the Gospel and be saved, so help you God.
