1 John 2:3-11 Revised Standard Version Catholic Edition (RSVCE)
3 And by this we may be sure that we know him, if we keep his commandments.[a] 4 He who says “I know him” but disobeys his commandments is a liar, and the truth is not in him; 5 but whoever keeps his word, in him truly love for God is perfected. By this we may be sure that we are in him: 6 he who says he abides in him ought to walk in the same way in which he walked.

29 “Lord, now lettest thou thy servant depart in peace,
33 And his father and his mother marveled at what was said about him; 34 and Simeon blessed them and said to Mary his mother,
“Behold, this child is set for the fall[b] and rising of many in Israel,
