Roman Catechism 24.14

Chapter 24 — Part III: The Decalogue — The First Commandment

Section 14. Their Intercession, therefore, we ought to invoke, because they always see tile face of God, and are constituted by Him the willing advocates of our salvation. The Scriptures bear witness to such invocation. Jacob entreated the Angel with whom he wrestled to bless him; nay, he even compelled him, declaring that he would not let him go until he had blessed him. And not only did he invoke the blessing of the Angel whom he saw, but also of him whom he saw not. The angel, said he, who delivers me from all evils, bless these boys.
