Note 1119 — Chapter VIII · RISE OF ECCLESIASTICAL MARRIAGE: THE CHURCH DEVELOPS AND ADMINISTERS MATRIMONIAL LAW

The canonists distinguished cognatio from affinitas. There are three sorts of cognatio: (1) consanguinitas; (2) cognatio legalis, or adoption; (3) cognatio spiritualis, arising in a participation in the same sacrament: Esmein, op. cit., 335 ff., 374 ff. On the whole subject see Niemeier, De conjugiis prohibitis, comprising ten separate dissertations with critical and bibliographical "supplementa," but relating largely to post-Reformation doctrine; Sanchez, Disput. de sto. mat. sac., II, 1-402; Tancred, Summa de mat. (ed. Wunderlich), 16 ff.; the monograph of Eichborn, Die Ehehinderniss der Blutsverwandtschaft nach kan. Rechte (Breslau, 1872); Schulte, Lehrbuch, 355-57; Friedberg, Lehrbuch, 337, 359; Sehling, Die Wirkungen der Geschlechtsgemeinschaft (impotence); Geary, Marriage and Family Relations, 20 ff.; Pollock and Maitland, Hist. of Eng. Law, II, 383 ff.; Freisen, Geschichte des can. Eherechts, 371 ff.; Jeaffreson, Brides and Bridals, I, 108 ff.; II, 306 ff.; Morgan, Marriage, Adultery, and Divorce, I, 199 ff. The Catholic doctrine is set forth at great length by Scheicher-Binder, Praktisches Handbuch, 8-354; and in Perrone, De mat. christ., II, 31 ff.
