Papal Records Reveal 37,916 Petitions from Illegitimate Children of Clergy (1449-1533)

Newly analyzed historical records from the Vatican's Apostolic Penitentiary show that between 1449 and 1533, the papacy processed an astonishing 37,916 petitions from individuals born out of wedlock seeking special permission to join the Catholic Church. This extensive data sheds light on the widespread challenge to clerical celibacy during the late medieval and early modern periods.

According to the research, clergymen were identified as the fathers in approximately 60% of these cases. The majority of these fathers held holy orders, including sub-deacons, deacons, and priests, with many illegitimate children reportedly born from relationships between priests and their housekeepers. This suggests a significant, albeit unofficial, deviation from the Church's celibacy requirements.

The petitions were primarily submitted by illegitimate young men seeking dispensations to be ordained to holy orders, appointed to ecclesiastical offices, or to hold benefices. The Church's canon law, particularly since the Second Lateran Council in 1139, strictly forbade illegitimate children from becoming priests, necessitating these special papal permissions, known as "defect of birth" dispensations.

The sheer volume of these requests, as highlighted by historian Kirsi Salonen in "A Sip from the 'Well of Grace': Medieval Texts from the Apostolic Penitentiary," underscores the prevalent issue of clerical concubinage and its societal impact. The data indicates that a considerable number of individuals entering the priesthood during this era were, in fact, the illegitimate sons of existing priests.

This historical phenomenon reveals the practical complexities and human realities within the Church's strictures on celibacy. The Apostolic Penitentiary, as the primary office for granting such graces, played a crucial role in navigating these social and ecclesiastical challenges, often allowing individuals to pursue clerical careers despite their birth status.
