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.[5] He discussed a distinction between killing in warfare (a sin), and in self-defense in battle.[6][7] Heavy penances for homosexual acts were imposed on older men.[8] The work is also a source for information about surviving pagan practices[9].
It was written in five volumes, at Ebbo's request[10]. Ebbo's intention was to have a normative penitential; Halitgar set aside tariffs of penances for exhortations.[11][12] 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[13]. At this point, "the books used by confessors began to consist more and more of instructions in the style of the later moral theology"[14].
