Organization of the Christian Congregation
From the time of Moses onward, the Jewish nation was in a unique position—it served as the congregation of God. That congregation was highly organized by God under older men, heads, judges, and officers. (Josh. 23:1, 2) But the Jewish nation lost its privileged position because it rejected Jehovah’s Son. (Matt. 21:42, 43; 23:37, 38; Acts 4:24-28) On Pentecost 33 C.E., the Christian congregation of God replaced the congregation of Israel. How was this Christian congregation organized?
Already on the day of Pentecost, the disciples were “devoting themselves to the teaching of the apostles,” indicating that they began with a unity based on teaching. From that first day, they met together “with one accord.” (Acts 2:42, 46) As the disciple-making work spread, congregations of believers began to form, first in Jerusalem and then outside Jerusalem. (Acts 8:1; 9:31; 11:19-21; 14:21-23) It was their custom to assemble together in public places as well as in private homes.—Acts 19:8, 9; Rom. 16:3, 5; Col. 4:15.
What kept the expanding Christian congregation from becoming a loose association of independent local congregations? They were united under one Leader. From the beginning, Jesus Christ was the appointed Lord and Head of the congregation, and he was recognized as such by all the congregations. (Acts 2:34-36; Eph. 1:22) From the heavens, Christ actively directed the affairs of his congregation on earth. How? By means of holy spirit and angels, put at his disposal by Jehovah.—Acts 2:33; compare Acts 5:19, 20; 8:26; 1 Pet. 3:22.
Christ had something else at his disposal for maintaining the unity of the Christian congregation—a visible governing body. At first, the governing body was made up of the faithful apostles of Jesus. Later, it included other older men of the Jerusalem congregation as well as the apostle Paul, even though he did not reside in Jerusalem. Each congregation recognized the authority of this central body of older men and looked to it for direction when organizational or doctrinal issues arose. (Acts 2:42; 6:1-6; 8:14-17; 11:22; 15:1-31) With what result? “Therefore, indeed, the congregations continued to be made firm in the faith and to increase in number from day to day.”—Acts 16:4, 5.
The governing body, under the direction of holy spirit, supervised the appointment of overseers and assistants, ministerial servants, to care for each congregation. These were men who met spiritual qualifications that applied in all the congregations, not merely standards set locally. (1 Tim. 3:1-13; Titus 1:5-9; 1 Pet. 5:1-3) Overseers were urged to follow the Scriptures and submit to the leading of holy spirit. (Acts 20:28; Titus 1:9) All in the congregation were encouraged to ‘be obedient to those taking the lead.’ (Heb. 13:17) In this way unity was maintained not only within each congregation but within the Christian congregation as a whole.
Even though some men held positions of responsibility, there was no clergy-laity distinction among the first-century Christian witnesses of Jehovah. They were all brothers; there was but one Leader, the Christ.—Matt. 23:8, 10.
An organized religion is nothing new even now. Most religions have some organization even if it is a lose one and not necessarily doing the will of God but still it's an organization.
Why should the JW's not be organized and condemned for that?
Ones who do not agree with religions are usually the ones that do their own thing which is not accepted by the Bible.
