Parousia

The term 'Parousia' derives from the Greek word for 'coming' or 'presence' and designates, in Catholic theological usage, the glorious return of Christ at the close of history. Disputes over how to interpret apostolic language about this event—particularly in the Pauline epistles—prompted the Pontifical Biblical Commission to issue a formal reply on June 18, 1915, addressing exegetical controversies surrounding the timing and nature of the Parousia as described in St. Paul's letters. The immediate occasion was a set of interpretive questions focused on 1 Thessalonians 4:15–17, where Paul's wording raised the question of whether he implied that the Parousia would occur within his own lifetime or that of his readers. Alongside this exegetical dispute, a broader theological concern arose over how to protect the inerrancy of inspired Scripture while accounting for texts that might appear to place the Parousia at an imminent, calculable moment. The Commission's replies drew upon patristic interpretation, notably that of John Chrysostom, as well as grammatical analysis of the Greek text, to adjudicate these contested readings. Separately, later theological reflection—including work of the International Theological Commission in 1990—identified a long-running tendency to relocate eschatological fulfillment within historical time rather than at a transcendent, concluding divine act, tracing this tendency in part to the spiritual heritage of Joachim de Fiore and noting its expression in certain strands of liberation theology.

Catholic doctrine holds the Parousia to be the decisive moment of God's final action in history, when Christ will return in glory, the dead will be raised, and the Last Judgment will disclose God's definitive victory over evil. The Catechism affirms that the resurrection of the dead is closely associated with Christ's Parousia, citing the Pauline image of the Lord descending and the dead in Christ rising. This resurrection is understood to occur 'at the last day' and 'at the end of the world,' grounded in faith in Christ as the resurrection and the life, and in God's creative power. Catholic eschatology maintains a tension between two truths held simultaneously: Christ already reigns, and yet that reign remains to be brought to its fulfillment 'with power and great glory' through the King's return. Until that return, evil remains a real force in the 'trial' of history, even though it has been decisively defeated by Christ's Passover. The Catechism further teaches that the Parousia will bring about the definitive triumph of good over evil, the arrival of the Kingdom of God in its fullness, and the renewal of the universe itself. The Church, in this framework, will receive her perfection in the glory of heaven when the 'renewal of all things' arrives. Parousia thus encompasses both a personal dimension—Christ's final dealing with the living and the dead—and a cosmic dimension involving the transformation of all creation.

The 1915 Reply of the Pontifical Biblical Commission addressed three principal interpretive questions. First, concerning 1 Thessalonians 4:15–17, the Commission answered in the negative to the proposition that Catholic interpreters may reject the traditional reading on the grounds that Paul included himself and his readers among those who would survive to meet the returning Christ. Second, the Commission rejected the methodological claim that inspired authors, in expressing 'human feelings,' could convey error or deception; it answered in the negative to the permissibility of such an approach as a means of resolving apparent scriptural difficulties. Third, the Commission affirmed that Paul 'said nothing at all which does not agree perfectly' with Christ's proclamation that no human being knows the time of the Parousia. Patristic interpretation, especially that of John Chrysostom, was invoked as a resource for resolving the grammatical and syntactical questions that had been placed in dispute. The argument that Paul's language could be read as a conditional construction—rather than an unconditional assurance of immediate arrival—was part of the interpretive environment the Commission sought to clarify. The Catechism, for its part, underscores that Christ's coming could occur 'at any moment,' while insisting that 'it is not for you to know times or seasons' fixed by the Father's authority. This dual emphasis on readiness without calculation governs the Catechism's practical exhortation to watchfulness. The 1990 International Theological Commission warned that 'violence is done to the texts' when the Parousia is explained as a permanent or ongoing event rather than a specific concluding act, and cautioned that interpretations according to which the dead have 'already risen' while the body remains in the grave risk 'doctrinal confusion.'

The sources available do not document the specific reception of the 1915 Reply in subsequent academic or ecclesiastical venues—no particular critics, supporters, or seminary curricula can be named on the basis of the materials consulted. What can be established is that the core concerns animating the 1915 Reply persisted in later official theological reflection. The International Theological Commission's 1990 work addressed the same fundamental issue: the danger of reducing the Parousia to an innerworldly or purely symbolic event. That later document explicitly identified a tendency, associated in part with the heritage of Joachim de Fiore and with certain liberation theology approaches, to treat transcendent salvation as secondary and to relocate the eschaton within the immanent flow of history. By naming this tendency and contrasting it with the New Testament's presentation of the Parousia as a culminating divine event, the 1990 Commission demonstrated the enduring relevance of the interpretive framework first formally articulated in 1915. The Catechism's treatment of the Parousia as both a specific future event and a present orientation of liturgical life reflects the same doctrinal commitments: resisting speculative date-setting, affirming the bodily and cosmic dimensions of resurrection, and grounding Christian hope in the realism of Christ's return rather than in symbolic interiorization.

The Parousia retains a structuring role across several dimensions of Catholic life and thought. Liturgically, the Catechism states that from the earliest Christian community 'until the parousia,' it is the same Paschal mystery that the Churches of God celebrate in every place, meaning that every Eucharistic gathering is oriented toward Christ's definitive return. The Catechism explicitly connects participation in the Eucharist with a foretaste of resurrection hope, and identifies the prayer Maranatha—'Our Lord, come!'—as the expression Christians use, above all in the Eucharist, to hasten Christ's return. The Lord's Prayer, in the Catechism's treatment of its final doxology, is understood to include both a petition for Christ's return and a request for the kingdom's growth in the present. Ecclesiologically, the Catechism ties the Church's catholicity to the horizon of the Parousia, affirming that the Church is catholic 'until the day of the Parousia,' thereby grounding the universality and continuity of her sacramental mission in the promise of Christ's final coming. Morally, the expectation of an event whose timing remains unknown to any human mind generates an ethic of watchfulness, faithfulness, and resistance to complacency rather than of speculative calculation. The Parousia thus functions in Catholic theology not as an abstract terminal point but as the living eschatological horizon that shapes worship, hope, and moral seriousness in every age of the Church.
