To the extent possible, all congregations worldwide study the same material each week. Meetings of Jehovah's Witnesses open and close with prayer. ‘Kingdom kings' are sung at most meetings, as well as at assemblies and conventions. Dress for meetings is local formal attire. For instance, in most Western countries, this consists of a suit and tie for males, and conservative dresses/skirts for females. Meetings are free to attend, and are open to the public.
Place of Worship Jehovah's Witnesses call their meeting places "Kingdom Halls" instead of churches. The original reason for this is because the Witnesses preach about God's Kingdom. The Witnesses emphasize the gathering or "congregation" of people, rather than the physical location.Kingdom Hallschurches

Belief cont’d The Salvation Army believe that there are three persons in the Godhead - the Father, the Son and the Holy Ghost, undivided in essence and co-equal in power and glory. They also believe that in the person of Jesus Christ the Divine and human natures are united, so that He is truly and properly God and truly and properly man.
Belief cont’d The first parents were created in a state of innocency, but by their disobedience they lost their purity and happiness, and that in consequence of their fall all men have become sinners, totally depraved and as such are justly exposed to the wrath of God.
Place of Worship Unusual places for worship! In Victorian times, Christian worship in Britain normally took places in the many churches and chapels of the different denominations. William and Catherine Booth, who found the Salvation Army, found that the very poor people whom they wanted to reach, did not want to enter such buildings. The answer was to preach in the streets and the fields, in tents, in hippodromes and in music hall buildings. Later in the 19 century other Christian groups copied their tactics and they later build meeting house.
When did it began The denomination grew out of the Millerite movement in the United States during the middle part of the 19th century and was formally established in 1863.  Among its founders was Ellen G. White, whose extensive writings are still held in high regard by Seventh- day Adventists today.
