The Church is holy because God makes her members holy by union with him. God sanctifies the Church by drawing her into his divine life through the union effected by the birth, death, burial, resurrection, and ascension of Christ. The faith and life of the His Church participate in the holiness of God by expressing the divine life in doctrine and practice through ongoing theosis. Immorality separates one from God and His Church.
The word "catholic", which was first coined by Ignatius of Antioch, means universal, whole, and complete; a term referring to the universal nature of Christ's Church. However, due to the influence of the Roman Catholic Church in the West, the words "catholic" and "catholicity" are usually understood as a reference to the Roman Catholic Church alone. We are Catholic, but certainly not Roman Cahtolic.
The term "apostolic" means "of the Holy Apostles" of Christ, referring to the fact that just as the apostles received their authority from the Son (Matthew 28:16-20; John 20:21), the apostles passed on that same authority by ordaining others. This succession has continued. Thus, there is an apostolic succession by which all the Presbyters of the Assemblies of Christ are able to trace their ordinations back to the apostles of the infant Church founded by Jesus Christ in the first century. In this sense, then, the Assemblies of Christ is called apostolic.
We are part of the One, Holy, Catholic, and Apostolic Church founded by Jesus Christ and His apostles, yet, we are a Living, Vibrant and
Passionate Modern Assembly. We have blended the Ancient Apostolic Faith with the powerful Pentecostal-Charismatic
renewal movements of the last century ~ all designed to draw believers into a living and life-giving relationship with the Triune God!
The word "Orthodox" comes from the Greek orthos ("straight" "correct" "true" "right") and doxa ("glory"), which expresses the idea of "correct glory", or in other words, "correct worship". For the ancients, this includes the adherence to accepted creeds and teaching. We embrace the Apostles, Nicene-Constantinopolitan, Athanasius, and Chalcedonian Creeds, the creeds of the unified church.
Ignatius, the Apostle of Antioch*, coined the term "catholic" as early as AD 105 to express the idea of a universal, whole, and complete Church, and for the first thousand years of Christianity, for the most part, there was only ONE worldwide Church with many Assemblies. Although there was liturgical diversity, Christians held to common doctrines and faith. Moreover, they embraced apostolic succession and a conciliar form of Church government. No matter where Christians lived, everyone was part of the same Church and essentially believed the same thing.
However, the unified Church began to split towards the end of the first millennium, and has been splitting and re-splitting over and over again ever since. Now, there are over 30,000 denominations and 40,000 church organizations. This was never the plan of Christ! His heart cry has always been that His Church would be one just as He and the Father are one (John 17:16-20). Therefore, we are endeavoring to cooperate with the very heart of Christ by keeping the unity of the Spirit as we fully embrace the unity of the faith as understood before the Great Schism.
We do not see ourselves as the One True Church in all her fullness. We only see ourselves as part of the One True Church visible family, united by the doctrines, sacraments, and faith of the ancient unified church, to include an apostolic succession and a conciliar Church government. We believe that to the degree that all His people move closer to the ancient faith of the unified church, to that degree we will be fulfilling the very heart cry of Christ ~ become one as He and the Father are one (John 17:11-23). We are doing our part!
*Ambrose asserts that all bishops were called apostles at first (Com. Eph. iv; Gal. i. 1).
