阿彌陀經通贊疏 2.7

2.7

贊曰：此第四明化主、第五辨說法也。阿彌陀上已解，自下經亦有自說處。現在者揀於過未，說者演說，法者執持名號之法，即是教法也。阿彌陀佛長為眾生演說妙法轉令精進，故慈悲廣大利物弘深，現初地之報身、化無邊之根器，故云今現在說法。

The Commentary says: This is the fourth, clarifying the teaching master, and the fifth, discerning the exposition of the Dharma. "Amitābha" has already been explained above, and later in the sūtra itself there is also a place where it explains it. "At present" excludes the past and future. "Expounding" means delivering, and "Dharma" refers to the method of holding fast to the name, which is the teaching Dharma. Amitābha Buddha constantly expounds the wondrous Dharma for sentient beings, progressively making them vigorous; thus his great kindness and compassion are vast and his benefiting of beings is profoundly great, manifesting the reward body of the first ground and transforming limitless capacities; hence it is said, "who is at present expounding the Dharma."
