1. The general ministry of all baptized believers
Every truly Christian person was anointed and appointed and called to the general ministry or office of all believers at his or her baptism. Matt. 28:19 & Acts. 8:12 cf, Ex.19:3-8 & Num, 11:29 & Joel 2:16,28-29 & Acts 2:17,38-39 & I Cor. 12:13-20,26 & Gal. 3:27-28 & Eph, 4:4-5,12-13,16 & I Pet, 2:9, So also Martin Luther, the Belgic Confession, the Heidelberg Catechism, the Westminster Confession of Faith, and the Westminster Larger Catechism.1
By virtue of this general ministry, all Christians are to be Christ's prophets and priests and kings at all times and in everything they do. Hence, all female Christians too are "heirs together" with all of their Christian brothers, and. are themselves to be Christ's prophetsses and priestesses and queens — all the time. I Pet. 3:7 cf. I Cor. 10:51 & Eccl. 3:1-13 & 5:18-20 & 9:7-10. Cf. also F.N. Lee's 1977 Principles of Biblical Church Government, and especially the section there on The Office of All Believers. Indeed, every human being should be involved in serving God as a "minister" alias a "servant" of the Lord. Rom, 13:4 cf, I Tim, 1:12 & I Pet, 4:10-11.
