In Hebrew, it is stated in pure vessels, indicating that even to this day, in God's house, that is in the church, the children of Israel, who contemplate God in their hearts, present spiritual sacrifices with the fruits and virtues of their souls through pure vessels, representing their holy bodies. Concerning this, the apostle states, "Do you not know that you are the temple of God, and that the Holy Spirit dwells in you" (1 Cor. 3:16). The Lord further asserts that He will take from among them priests and Levites so that those who are saved may preach to the nations. One among them reminds us not to be disregarded as servants of Christ and stewards of the mysteries of God (1 Cor. 4:1). The Evangelist Luke notes, "As they delivered to us, who at first were eyewitnesses and ministers of the word" (Luke 1:2).
We previously read that they shall be "priests of the Lord with Me" (Isaiah 61:6). Just as there exists an inward Jew, one who is spiritually circumcised (Rom. 2), it is written, "We are the circumcision, who serve God in the spirit" (Phil. 3:3), offering spiritual sacrifices to please God and engaging in heartfelt psalmody. Likewise, the priests and Levites are inwardly those who do not follow lineage but adhere to the order of faith. It may be that he refers not only to the apostles and apostolic figures leading the churches sprung from the Jewish people, but also to the nations mentioned—those from the sea, Africa, Libya, Cappadocia, Italy, Greece, and the islands—whose inhabitants initially did not hear of the Lord or behold His glory, but who will later be transformed into priests. Thus, what were once the last will become the first, and what were once the first will become the last.
