Executive summary

Pope Leo XIII consistently taught the absolute value and indissolubility of Christian marriage, framing divorce and remarriage as a moral and social ill that undercuts the sacramental sign of Christ’s union with the Church [1] [2]. The supplied reporting does not contain the writings of Pope Leo I (d. 461), so any specific attribution to Leo I on Communion for divorced-and-remarried Catholics cannot be documented here; contemporary magisterial texts and later interpreters, however, have long treated divorced-and-remarried Catholics as generally ineligible for Communion absent annulment or a disciplined pastoral exception [3] [4] [5].

1. Pope Leo XIII: rigorous defense of marriage that implies exclusion from sacramental union

Pope Leo XIII’s encyclicals and addresses emphatically defended marriage as an indissoluble social and sacramental institution and warned that legal or social tolerance of divorce produced widespread moral corruption—an argument he developed in Arcanum and other writings on Christian marriage [2] [1]. Those writings do not lay out a modern canonical rubric about reception of the Eucharist in technical terms, but they establish the theological premise the Church has used to bar those who contract a civil remarriage without annulment from sacramental communion: the remarried state objectively contradicts the spousal sign of Christ and the Church [2] [1] [3]. Contemporary commentators who invoke Leo XIII to oppose reforms allowing remarried persons access to Communion argue that his emphasis on indissolubility makes any loosening an “aberration” from longstanding orthodoxy [6].

2. Pope Leo I: absence of primary texts in the provided reporting and the limits of attribution

The material provided for this inquiry contains no primary or secondary texts from Pope Leo I (Leo the Great) addressing reception of Communion by divorced and remarried persons, so no direct teaching of Leo I on this specific pastoral question can be cited here. In general patristic and ecclesiastical tradition Leo I is known for strong teachings on the unity of Church and doctrine, but without the relevant sources one must not assert a specific magisterial pronouncement from him on Eucharistic discipline for remarried divorcees (no supporting source in the provided set).

3. How later magisterium formalized exclusion and the language used to justify it

The modern disciplinary line—prominently restated by the Congregation for the Doctrine of the Faith and by papal documents—frames the issue as objective incompatibility: those who divorce and civilly remarry without annulment “are unable to be admitted” to Communion because their state “objectively contradict[s] that union of love between Christ and his Church which is signified and effected by the Eucharist,” and admission would risk confusion about the indissolubility of marriage [3] [4]. St. John Paul II’s Familiaris Consortio reaffirmed the norm that remarried persons must separate or live in continence to be admitted, and subsequent Vatican statements have reiterated this as the ordinary discipline [3] [7].

4. Contemporary dispute: case-by-case mercy versus juridical consistency

Since Pope Francis’s Amoris Laetitia, a vigorous debate has unfolded: critics cite Leo XIII and the classical magisterium to insist continuity and to call any admission to Communion an aberration [6] [1], while defenders of a pastoral, case-by-case approach argue that Francis’s text opens a moral space for some remarried Catholics—those judged not fully culpable—to receive Communion under discernment by pastors [5] [8] [9]. Vatican congregational documents and commentators such as Cardinal Ratzinger’s 1998 text continue to express the traditional normative rule, whereas authors sympathetic to Amoris emphasize mitigating factors, internal forum procedures, and the pope’s pastoral language [4] [5] [8]. The disagreement is therefore not merely theological but interpretive and institutional: some actors use Leo XIII’s emphasis on indissolubility to resist pastoral change, while others read recent papal practice as development within continuity [6] [9].

5. Bottom line — what can be said with the available sources

From the supplied material, Pope Leo XIII’s teaching firmly upholds marriage’s indissolubility and supplies the theological basis for excluding divorced-and-remarried Catholics from Communion absent annulment or living in continence [2] [1] [3]. No direct teaching from Pope Leo I on this specific Eucharistic question is present in the reporting, so that attribution cannot be documented here; the broader magisterial practice summarized by Congregation documents and later papal exhortations explains how Leo XIII’s marriage theology has been applied to Eucharistic discipline in subsequent centuries [3] [4] [5]. Contemporary controversy centers on whether pastoral exceptions articulated in Amoris Laetitia represent a legitimate, case-by-case development or a rupture from the tradition to which Leo XIII belonged, a dispute evident in the sources and driven as much by interpretive agendas as by disputed facts [6] [9] [8].
