Sermon — Behold I Send My Angel (Ecce Ego)

(b) In order to fulfill their duty concerning the divine things coming down from heaven, angels came to him and served him, as Matthew 4:11 reads. (The mission of the angels was completed as Christ began to reveal himself; mediators were not needed anymore. What had been announced by angels and prophets and expected by the people for ages (cf. Matt 13:16–17) now became true (cf. ST I-II.98.3; II-II.172.2).)

(c) In order to render examples and proofs of spiritual perfection, the angels of God had gone to meet Jacob, and when he had seen them, he said: ‘these are the encampments of God’; (Gen 32, 33:12.) (The words quoted are from Genesis 32:1–2.)
