阿彌陀經疏 1.40

1.40

皆是大阿羅漢，顯位也。謂諸比丘非是學人，皆無學極果也。羅漢含三義：一、應供，堪為人天福田故，此乃乞士之果也；二、殺賊，斷盡煩惱故，此乃破惡之果也；三、無生，不受後有故，此乃怖魔之果也。

“All were great arhats” reveals their rank. This means these bhikṣus were not trainees (śaikṣa); all possessed the ultimate fruit of non-training (aśaikṣa). “Arhat” contains three meanings: first, “worthy of offerings,” because they are capable of serving as fields of merit for humans and devas—this is the fruit of the “beggar of sustenance”; second, “slayer of thieves,” because they have cut off afflictions completely—this is the fruit of the “destroyer of evil”; third, “unborn,” because they do not undergo subsequent existence—this is the fruit of the “terrorizer of Māra.”
