I. From Apostles to Apostolicity apostolos: Jesus (Heb 3:1), the Twelve (Matt 10:2),
Paul and Barnabas (Acts 14:14), others (Rom 16:7, Phil 2:25, 2 Cor 8:23).
Witness to the resurrection (Acts 1:26),
Head of Israel (Rev 21:14),
Foundation of the Church (Eph 2:20),
Missionary of the Gospel (Matt 10:2).
So the Twelve Apostles are irreplaceable foundations of the later Church.
Apostolicity names the later Church's fidelity to the earliest Church.
Apostolicity describes the Church's center and its mission across boundaries.
II. Catholic Apostolicity
The Holy Spirit communicates the Church through apostles' successors.
Thus bishops (episkopoi) and elders (presbuteroi) (Acts 20:28, Titus 1:5).
Antioch, Rome, and other prominent cities soon had monarchical bishops:
Polycarp of Smyrna, 100; Clement of Rome, 90; Ignatius of Antioch, 67.
III. Protestant Apostolicity
Formal apostolicity seemed at odds with biblical apostolicity.
Reformers: Apostolicity is fidelity to the apostles' canonical writings (Scripture).
Reform might change polity (Reformed, radical) or not (Anglican, Lutheran).
No clear New Testament pattern replaces episcopal leadership.
General models: Episcopal, presbyterian, congregational.
IV. "Spirit-Baptism" as (Sharing Christ's) Charismatic Anointing
All assume Church leadership is charismatic (Spirit-given) leadership.
Must charismata have a formal episcopal medium (Acts 8:17, 1 Tim. 4:14)?
Or arise spontaneously (Acts 10:44-48) and be confirmed in other ways?
