"By creating the human being man and woman, God gives personal dignity equally to the one and the other. Each of them, man and woman, should acknowledge and accept his sexual identity."
"Deus, creaturam humanam virum creans et mulierem, utrumque pari donavit personali dignitate. Ad unumquemque pertinet, ad virum et mulierem, suam sexualem agnoscere et acceptare identitatem."
Catechism of the Catholic Church no. 2393 (under the Sixth Commandment; English, Latin). Identitas is post-classical, apparently 4th century and following. Blaise doesn't carry the modern sense, but the DMLBS (the other dictionary of medieval Latin to which I have immediate access from here at home) offers the following, no. 3a of 9: "identity, condition or fact that person or thing is itself and not something else" (the OED gives the 8th century for that sense, and 1756 for 'individuality, personality' as a sense of the French identité).
