Eastern Orthodox churches occasionally practise what is seen by other Christians as "re-Chrismation", in that they usually chrismate/confirm – and sometimes rebaptize – a convert, even one previously confirmed in other churches. The justification is that the new Chrismation (or baptism) is the only valid one, the earlier one being administered outside of the Church and hence being little more than a symbol. The Eastern Orthodox will also chrismate an apostate from the Orthodox Church who repents and re-enters communion. According to some interpretations, the Eastern churches therefore view confirmation/Chrismation as a repeatable sacrament. According to others, the rite is understood as "part of a process of reconciliation, rather than as a reiteration of post-baptismal chrismation".
