• This paper responds to the question what is the origin and nature of apostolicity and how it is
    demonstrated? The investigation examines the meaning of apostolicity found in the New
    Testament, its significant transition through the post-apostolic period, and the consequence on
    contemporary understanding. The dilemma of the first and second century-generation
    Christians was how to understand apostolicity in light of the disappearance of the ‘sacred triad’
    (apostles, prophets and teachers). The emerging principles of discontinuity, transference,
    transformation and succession carved the road to canonisation, bishop-centrism and episcopal
    systemisation. The Pentecostal anchorage in the outpouring of the Spirit at Pentecost is
    determinant in qualifying apostolicity; while emphasising agency and function, it also turns
    attention to the Person of the Spirit. This leads necessarily to an examination of the Trinity,
    ontologically and relationally, and therefore brings a fuller response to the research question.
    Subsequent exploration of the non-hierarchical, ‘intra-Trinitarian’ relationship will demonstrate
    an apostolic archetype. This contribution seeks to restore the Trinity to apostolic thinking in
    response to the historical construct by defining the nature of apostolicity in Godhead, and to
    argue apostolicity as a response to subordinate suppositions. It concludes with a proposed
    basis for renewed self-understanding as Trinitarian extension.
