Apostolicity refers to the quality or state of being apostolic, which encompasses the teachings, authority, and mission of the apostles as established in the New Testament. The term is significant in Christian theology as it underscores the continuity and authenticity of the church's doctrine and practices as rooted in the teachings of Jesus Christ and his apostles. The concept of apostolicity is crucial for the legitimacy of church authority and the transmission of the faith through generations.In biblical terms, apostolicity can be linked to passages such as Ephesians 2:19-20, which describes the church as being "built on the foundation of the apostles and prophets, with Christ Jesus himself as the chief cornerstone." This foundation signifies that the teachings and leadership of the apostles are essential for the church's identity and mission. Furthermore, the apostolic mission is exemplified in Matthew 28:19-20, where Jesus commissions his disciples to make disciples of all nations, indicating that the authority given to the apostles is meant to be passed down through the generations. This understanding reinforces the importance of maintaining fidelity to the original teachings and practices of the apostles as essential for the church's witness and mission in the world.
