ANSWER: There is no authority in the Bible for an earthly headquarters. To add an earthly headquarters to the organization of the church would be to add to God’s Word, resulting in sin (Revelation 22:18-19). Also, if there were an earthly headquarters, there would have to be an earthly head. Paul tells us in Ephesians 1:22 that there is only one (the) Head who is Jesus Christ! Our Head, who established the kingdom/church (Matthew 16:18-19) and paid the price for it (Acts 20:28), is enthroned at the right hand of God (Acts 2:29-36) as Lord of lords and King of kings (Revelation 17:14) over His kingdom (Daniel 7:13-14). Since our Head, our King, is in Heaven, our headquarters is also in Heaven.
