What... the "definitions" that you chose to select? And I'm supposed to just take your word that's the one that was intended? BOTH words can be (and ARE in the cited portion of the catechism) dealing specifically with actions. 2357 makes this quite clear.
You have demonstrated that you don't understand what the Church is saying here. But it's quite clear in the paragraph you cited. Those candidates who cannot remain chaste (regardless of the reason) may not be priests. Those who CAN remain chaste (regardless of which way their "orientation" would lead them to temptation) may.
No I understand quite well what the Church is saying today and what it was saying in 1961.
