Christian churches cannot be called apostolic as there is only
one Church, the Catholic Church, that is truly apostolic. There are
some churches that put the term apostolic in their name; however,
this is a misnomer as they cannot exhibit a line of succession from
the apostles to the present. If by the Christian Church you mean
the Catholic Church then the answer is obvious, every Bishop,
priest, and deacon has been ordained in the apostolic succession.
The four marks of Christ's Church are that it is "One, Holy,
Catholic, and Apostolic":' the Catholic meaning that it is
universal, and the Apostolic meaning that all its leaders are
ordain by men who were ordained by the Apostles. "Christian"
Churches, as in protestant churches are only apostolic in their
dreams.
