What were they called back then in the bible?
Did they call themselves the "first century governing body"?
Or "christian congregation"?
The WTBTS Inc printing and publishing factory belivies so, for they have added these "catch prases" to their literature.
Please note the references quoted from the WTBTS Inc's "publications" below:

Jehovah’s Organization
3 An organization is “an organized body ,” according to the Concise Oxford Dictionary. With that in mind, we understand that because the apostles organized first - century Christians into local congregations under the oversight of a governing body in Jerusalem, it is proper to speak of that “association of brothers” as an organization. (1 Peter 2:17) Jehovah’s Witnesses today have a similar organizational structure. The unity of the first - century body was strengthened by “gifts in men,” such as “shepherds and teachers.” Some of these traveled from congregation to congregation, while others were elders in local congregations. (Ephesians 4:8, 11, 12; Acts 20:28) Similar “gifts” strengthen the unity of Jehovah’s Witnesses today.

Accountable to a Governing Body ?
10 The purpose of headship is to preserve unity and ensure that “all things take place decently and by arrangement.” (1 Corinthians 14:40) To achieve this in the first century , a number of anointed Christians from the faithful and discreet slave class were chosen to represent the entire group. As subsequent events proved, the supervision exercised by this first - century governing body had Jehovah’s approval and blessing. First - century Christians gladly accepted the arrangement. Yes, they actually welcomed and were grateful for the fine results it produced.—Acts 15:1-32.
11 The value of such an arrangement still exists. Presently, the Governing Body of Jehovah’s Witnesses is composed of ten anointed Christians, all with decades of Christian experience behind them. They offer spiritual direction to Jehovah’s Witnesses, as did the first - century governing body . (Acts 16:4) Like the early Christians, the Witnesses gladly look to the mature brothers of the Governing Body for Bible-based direction and guidance in matters of worship. Though members of the Governing Body are slaves of Jehovah and of Christ, as are their fellow Christians, the Bible instructs us: “Be obedient to those who are taking the lead among you and be submissive, for they are keeping watch over your souls as those who will render an account; that they may do this with joy and not with sighing, for this would be damaging to you.”—Hebrews 13:17.

Theocratic Order Is Essential
12 A family that has strong but loving leadership and that is orderly is likely to be united and happy. (Ephesians 5:22, 33; 6:1) Jehovah is a God of peaceful order, and all those in his family regard him as “the Supreme One.” (Daniel 7:18, 22, 25, 27; 1 Corinthians 14:33) They also recognize that he has appointed his Son, Jesus Christ, the heir of all things and has delegated to him all authority in heaven and on earth. (Matthew 28:18; Hebrews 1:1, 2) With Christ as its Head, the Christian congregatian is an orderly, united organization. (Ephesians 5:23) To supervise the activities of the first - century congregations, there was a governing body made up of the apostles and other spiritually mature “older men.” Individual congregations had appointed overseers, or elders, and ministerial servants. (Acts 15:6; Philippians 1:1) Obeying those taking the lead promoted unity.—Hebrews 13:17.

Governing Body Takes Action
15 To preserve the unity of a family, occasionally a dispute may have to be settled. Suppose, then, that a spiritual problem had to be solved to preserve the unity of God’s family of worshipers in the first century C.E. What then? The governing body took action, making decisions on spiritual matters. We have a Scriptural record of such action.

14 Revelation of sacred truths was initially given through the nation of Israel. (Romans 3:1, 2) After 33 C.E., it was given through the first - century anointed Christian congregatian . Paul, speaking of first - century Christians, said: “It is to us God has revealed [the things prepared for those who love him] through his spirit.” (1 Corinthians 2:10; see also Revelation 1:1, 2.) Christendom’s doctrine of the immortality of the soul is derived from Greek philosophy. It was not revealed through God’s revelations to Israel or through the first - century congregation of anointed Christians.

4 On the other hand, marriage is not a Scriptural requirement for eldership. Jesus remained single. (Ephesians 1:22) Paul, an outstanding overseer within the first - century Christian congregatian , was then unmarried. (1 Corinthians 7:7-9) Today, there are many single Christians who serve as elders. Their single state probably leaves them more time to discharge their duties as overseers.

“Clean and Undefiled” From God’s Standpoint
4 The other two occurrences of the word thre·skei´a are in the letter written by the disciple James, a member of the governing body of the first - century Christian congregatian . He wrote: “If any man seems to himself to be a formal worshiper [“to be ‘religious,’” Phillips] and yet does not bridle his tongue, but goes on deceiving his own heart, this man’s form of worship [“religion,” Phillips] is futile. The form of worship [“religion,” Phillips] that is clean and undefiled from the standpoint of our God and Father is this: to look after orphans and widows in their tribulation, and to keep oneself without spot from the world.”—James 1:26, 27.

6 James does not enumerate all the things that Jehovah requires in connection with pure worship. In line with the general theme of his letter, which is faith proved by works and the need to keep free from friendship with Satan’s world, he highlights just two requirements. One is “to look after orphans and widows in their tribulation.” This involves true Christian love. Jehovah has always shown loving concern for orphans and widows. (Deuteronomy 10:17, 18; Malachi 3:5) One of the initial acts of the first - century governing body of the Christian congregatian was in behalf of Christian widows. (Acts 6:1-6) The apostle Paul gave detailed instructions for providing loving care for destitute elderly widows who had proved themselves faithful over the years and who had no family to help them. (1 Timothy 5:3-16) The modern-day Governing Body of Jehovah’s Witnesses has likewise issued precise instructions on “Caring for the Poor,” stating: “True worship involves looking after faithful and loyal ones who may be in need of material assistance.” (See the book Organized to Accomplish Our Ministry, pages 122-3.) Bodies of elders or individual Christians who show themselves negligent in this respect are omitting an important aspect of the form of worship that is clean and undefiled from the standpoint of our God and Father.
*** w83 3/1 p. 24 What Is Our Position Toward Opposers of the Truth? ***
11 What does all of that tell us? This: that there were problems of divisive thinking in the first - century Christian congregatian . There was opposition from within, from among those who were claiming to be a part of the congregation of God. And what was the cause? Paul said at Philippians 1:15: “Some are preaching the Christ through envy and rivalry, but others also through goodwill.” Today’s English Version mentions such ones as having an improper motive, being “jealous and quarrelsome.” Yes, the things written in times past do serve as a warning example to us, and more so now since we are living right at the end of the wicked system of things directed by the Devil.—2 Timothy 3:1-7.
