apostolic doctrine"; (ii) "the will to proclaim God's word"; (iii) "communion in the fundamental continuity of the Church, the Body of Christ, the faithful celebration of Baptism and the Eucharist"; (iv) "succession in the laying on of hands, the sign of ministerial continuity". According to Walter Kasper, the Reformed-Catholic dialogue came to belief that there is an apostolic succession which is important to the life of the Church, though both sides distinguish the meaning of that succession. Besides, the dialogue states that apostolic succession "consists at least in continuity of apostolic doctrine, but this is not in opposition to succession through continuity of ordained ministry". While the Lutheran-Catholic dialogue distinguished between apostolic succession in faith (in substantive meaning) and apostolic succession as ministerial succession of bishops, it agreed that "succession in the sense of the succession of ministers must be seen within the succession of the whole church in the apostolic faith". The Joint International Commission for Theological Dialogue Between the Catholic Church and the Orthodox Church asserts that apostolic succession means something more than just a transmission of authorities; it witnesses to the apostolic faith from the same apostolic faith, and in communion with other churches (attached to the apostolic communion). Apostolic tradition deals with the community, not only an ordained bishop as an isolated person. Since the bishop, once ordained, becomes the guarantor of apostolicity and successor of the apostles; he joins together all the bishops, thus maintaining episkope of the local churches derived from the college of the apostles. Churches claiming apostolic succession Churches that claim some form of episcopal apostolic succession, dating back to the apostles or to leaders from the apostolic era, include: the Roman Catholic Church the Eastern Orthodox Church the Oriental Orthodox Churches the Church of the East the Anglican Communion some Lutheran churches Old Catholics and other Independent Catholics (those incorporating the term "Catholic") some churches in the Convergence Movement The Anglican Communion and those Lutheran churches which claim apostolic succession do not specifically teach this but exclusively practice episcopal ordination. While some Anglicans claim it for their communion, their views are often nuanced and there is widespread reluctance to 'unchurch' Christian bodies which lack it. Roman Catholics recognize the validity of the apostolic successions of the bishops, and therefore the rest of the clergy, of the Eastern Orthodox, Oriental Orthodox, Church of the East, and Polish National Catholic Church.
