Halitgar (Halitgarius, Halitcharius, Halitgaire, Aligerio) was a ninth-century bishop of Cambrai (in office 817–831). He is known also as an apostle to the Danes, and the writer of a widely known penitential.
His De Paenitentia laid down qualities Christians should aspire to in their lives. He discussed a distinction between killing in warfare (a sin), and in self-defense in battle. Heavy penances for homosexual acts were imposed on older men. The work is also a source for information about surviving pagan practices.
It was written in five volumes, at Ebbo's request. Ebbo's intention was to have a normative penitential; Halitgar set aside tariffs of penances for exhortations. This work and the two attributed to Hrabanus Maurus were considered to supersede those written before, and were very influential, particularly in pre-Norman England. At this point, "the books used by confessors began to consist more and more of instructions in the style of the later moral theology".
