The Church
The Church is the Body of Christ, temple of the Holy Spirit, Eucharistic assembly, communion of local churches, and foretaste of the Kingdom. Apostolic succession is continuity of faith, sacramental ministry, and communion—not merely an unexamined chain of names.
Why it matters
Orthodox Christianity cannot be practiced as a self-authorized individual project. Christ gathers a people into visible communion.
Historical context
First Clement describes apostolic appointments; Ignatius presents bishop, presbytery, deacons, Eucharist, and unity; Irenaeus appeals to public apostolic succession against secret Gnostic claims.
Pastoral note
This module supports parish catechesis; it does not replace the guidance of the priest or catechist responsible for a person's reception into the Church. Local disciplines and preparation practices belong to the parish and bishop.

Primary sources
Ignatius writes to the Smyrnaeans:
Ignatius connects visible ecclesial unity with the bishop and the Eucharistic assembly.
See that you all follow the bishop, even as Jesus Christ does the Father, and the presbytery as you would the apostles; and reverence the deacons, as being the institution of God. Let no man do anything connected with the Church without the bishop. Let that be deemed a proper Eucharist, which is [administered] either by the bishop, or by one to whom he has entrusted it. Wherever the bishop shall appear, there let the multitude [of the people] also be; even as, wherever Jesus Christ is, there is the Catholic Church.

the ecclesiastical tradition from the apostles, and the preaching of the truth, have come down to us
Passage context and translation
