Some mortal sins cause automatic excommunication by the very deed itself, for example renunciation of faith and religion, known as apostasy,[26] desecration of the Eucharistic species,[27] and "a completed abortion".[28] Those mortal sins are so serious that the Church through law has made them crimes. The Church forbids the excommunicated from receiving any sacrament (not just the Eucharist) and also severely restricts the person's participation in other Church liturgical acts and offices. A repentant excommunicated person may talk to a priest, usually in a confessional, about their excommunication to arrange for the remission. Remission cannot be denied to someone who has truly repented their actions and has also made suitable reparation for damages and scandal or at least has seriously promised to do so.[29][30] However, even if excommunicated, a Catholic who has not been juridically absolved is still, due to the irrevocable nature of baptism, a member of the Catholic Church and therefore must still carry out their obligations of fulfilling their duties of attending Mass, Divine Liturgy, etc. on a Holy Day of Obligation, abstaining from meat on the Fridays of Lent, etc., albeit their communion with the Christ and the Church is gravely impaired. "Perpetual penalties cannot be imposed or declared by decree."[31] However, "the following are expiatory penalties which can affect an offender either perpetually".[32]
