Action Alert!

Catholic Dictionary




A statement that expresses a judgment by making a definite affirmation or negation. The doctrines of the Church, whether of belief or morals, are expressed by, or reducible to, propositions. They are categorical propositions because they make absolute and not merely hypothetical statements about what they affirm or deny. And they are necessary propositions because their predicate (what is said) is necessarily contained in or necessarily excluded from the nature or concept of the subject (about which something is said). (Etym. Latin propositio, representation, assertion; from proponere, to put forth.)
