II.1. Clerics.
(1) All who are ordained in grades of ecclesiastical ministry are generally called clerics.
Our teachers say that clerics, or those henceforth called clerics, are so named beacause we read that Matthias, chosen by lot, was the first who was ordained by the apostles [see Acts 1:26]. Also all those whom the leaders of the churches ordained in those times were chosen by lot. For "cleros" is translated as lot. Hence also inheritance is called kleronomia in Greek, and an heir kleronomos. (2) In like manner, therefore, they say that clerics are named by the fact that they are provided for in the "portion" of the Lord's inheritance, or by the fact that the Lord himself is their lot, as it is written concerning them, the Lord speaking: "I am your share and your possession" [Num 18:20]. Therefore it is fitting that those who possess God as their inheritance endeavor to serve God without any worldly impediment, and that they strive to be "poor in spirit" [Matt 5:3], so that they might be able to say, in accord with the psalmist: "The Lord is my chosen portion and my cup; you hold my lot" [Ps 15(16):5].
