A lapsed Catholic is a baptized Catholic who is non-practicing. Such a person may still identify as a Catholic and remains a Catholic according to canon law.
Interpretations
The Merriam-Webster Dictionary definition of "lapsed" in relation to "lapsed Catholic" is "no longer believing or following the teachings of a religion". The Oxford American Writer's Thesaurus associates the term "lapsed Catholic" as one who is backsliding. Lapsing is thus not necessarily connected with a lack of belief. However, author Daniel Ford links being a lapsed Catholic with rejection of Catholic teaching, either totally or by being an "à la carte Catholic". Other sources associate the term with abandonment of practice of the Catholic religion rather than with rejection of its doctrine. Thus the Cambridge Advanced Learner's Dictionary defines "lapsed", again in relation to "lapsed Catholic", as "no longer involved in an activity or organization", and the Oxford Dictionary speaks only of "no longer following the rules and practices of a religion or doctrine". Richard John Neuhaus distinguished between Catholic and Protestant ideas of what it means to be "lapsed" by quoting G.K. Chesterton, who remarked that a Protestant typically says he is a good Protestant, while a Catholic typically says he is a bad Catholic. For many, being a lapsed Catholic is just another way of being a Catholic.
According to Catholic belief, baptism "seals the Christian with the indelible spiritual mark of belonging to Christ. No sin can erase this mark, even if sin prevents baptism from bearing the fruits of salvation." Even the form of censure known as excommunication does not in itself make a person an ex-Catholic in the eyes of the Church: excommunicated persons are "cut off from the Church", barred from receiving the Eucharist and from taking an active part in the liturgy, but they remain Catholics according to Church doctrine. They are urged to retain a relationship with the Church, as the goal is to encourage them to repent and return to active participation in its life.
History
In the time of the persecution of Christians in the Roman Empire, many Christians, including clergy and even some bishops, were referred to as the lapsi as opposed to the stantes. Different attitudes developed within the Church towards the lapsed: some held they should never be readmitted to the Church before death, others were for demanding serious penance of them before readmitting them, while others again were still more lenient. The First Council of Nicaea insisted that any clergy who had lapsed were not to be readmitted to clerical rank. From 1983 a formal act of defection from the Catholic Church was recognised in the Code of Canon Law, making defectors ineligible for the privileges of membership of the Church, such as marrying in church. This form of defection was removed from the Code in 2009, and it was no longer possible to defect formally from the Catholic Church. In the religion question on the Republic of Ireland census, "lapsed Catholic" was collated separately for the first time in 2011, when 1,268 were recorded ; the 2016 census recorded 8,094.
Present canon law
Today, a Catholic who lapses to the extent of becoming an apostate, a heretic or a schismatic is automatically excommunicated, and, until the excommunication is lifted, is forbidden to have any ministerial part in the celebration of Mass or other worship ceremonies, to celebrate or receive the sacraments or to exercise any Church functions. This is an obligation that binds the excommunicated person. Unless the excommunication has been publicly declared by the Church and not merely incurred automatically, the excommunicated person cannot on that ground alone be publicly refused the sacraments, even by a priest who knows of it. However, to assist at the marriage of someone who has "notoriously" rejected the Catholic faith, a priest needs the permission of the ordinary and the same promises required by spouses in mixed marriages are also required. The Code of Canon Law lays down no particular penalty for a lapsing that consists of failure to fulfill the obligations to attend Sunday Mass and to receive Communion during Eastertide.
Colloquial names
Some lapsed Catholics attend Mass on special occasions like Christmas and Easter. Such lapsed Catholics are colloquially referred to by such terms as Cultural Catholics, Convenient Catholics, Submarine Catholics, Two-Timers, Chreasters, C&E Catholics, Poinsettia & Lily Catholics, CEOs, APEC, CAPE or PACE Catholics, CASE Catholics, CMEs, or A&P Catholics. "Cultural Catholic" is also used to refer to a non-religious member of a historically Catholic ethnic group, such as Austrian, Belgian, Bavarian, French, French Canadian, Filipino, Hungarian, Irish, Italian, Lithuanian, Maltese, Poles, Portuguese, Spaniards, Slovene, Slovak and Latin Americans.. In Brazil, the common term for Lapsed Catholic is "Católico Não-Praticante".
