In this time of Synod, “dubia” became more popular. The publication of a new set of questions addressed to Pope Francis by five longtime cardinals has once again turned the focus of Catholics to the place of “dubia” in the life of the Church.
What is dubia?
The word “dubia” — plural for a “dubium” — literally means, from the Latin, “doubts.” But another way of translating it is to see the word meaning “questions that seek clarification.” A dubium, then, is a request for clarity from a dicastery or office of the Roman Curia or even of the Holy Father himself on a matter of Church teaching, a liturgical issue, or a fine point of interpreting canon law. The questions most often arise from the daily issues of Church governance and liturgical and sacramental practice. In fact, dubia are a regular feature of the interaction between the Vatican’s various dicasteries and Catholic dioceses around the globe.
What Questions are Submitted?
A dubium is most often sent to one of three Vatican offices: the Dicastery for the Doctrine of the Faith, the Dicastery for Divine Worship and the Discipline of the Sacraments, and especially the Dicastery for Legislative Texts, which is asked to interpret the meaning or applicability of a canon in the Code of Canon Law.
Dubia can cover almost every imaginable topic. A few of the questions asked in recent decades include: “Can the title of minor basilica be granted to a cathedral?”, submitted to the Congregation for Divine Worship; “Are Mormon baptisms valid?”, sent to the Congregation for the Doctrine of the Faith; and “Are already-married candidates for the permanent diaconate required with their wives to practice perfect and perpetual continence after ordination?”, submitted to the Pontifical Council for Legislative Texts.
Most often, dubia are submitted by bishops, bishops’ conferences, or religious communities, but any Catholic may send them, as was shown in 2021 when three German lay Catholics from the Diocese of Essen submitted a dubium to the Congregation for the Doctrine of the Faith asking if the Church in Germany is in a state of schism as a result of the German Synodal Way.
Reponds to dubia
By custom, when a Vatican dicastery does answer a dubium, it is through a “Responsum ad dubium” (literally, a response to the doubt), and customarily, the response can be answered in the affirmative or the negative, “yes” or “no.” Almost always, the terse reaction is accompanied by a fuller explanation or commentary.
Very often as well, the answer from a dicastery is considered a “private response,” meaning it is not universally applicable nor can it be applied to address a situation in some other forum, even if the facts or circumstances are similar. How the response is issued matters as well, as a private reply by way of a letter has far less weight and far narrower applicability than a formal instruction or notification. Traditionally, the Dicastery for Divine Worship has published its “responsa” in the Notitiae, a publication issued bimonthly that until recently contained all important statements, documents, and responses pertaining to the liturgy and the sacraments. For those questions that require a formal statement, dicasteries will issue them publicly.
