First Reading: Sirach 4: 11-19
11 Wisdom inspireth life into her children, and protecteth them that seek after her, and will go before them in the way of justice.
12 And he that loveth her, loveth life: and they that watch for her, shall embrace her sweetness.
13 They that hold her fast, shall inherit life: and whithersoever she entereth, God will give a blessing.
14 They that serve her, shall be servants to the holy one: and God loveth them that love her.
15 He that hearkeneth to her, shall judge nations: and he that looketh upon her, shall remain secure.
16 If he trust to her, he shall inherit her, and his generation shall be in assurance.
17 For she walketh with him in temptation, and at the first she chooseth him. She will bring upon him fear and dread and trial: and she will scourge him with the affliction of her discipline, till she try him by her laws, and trust his soul. Then she will strengthen him, and make a straight way to him, and give him joy,
18 And will disclose her secrets to him, and will heap upon him treasures of knowledge and understanding of justice.
19 But if he go astray, she will forsake him, and deliver him into the hands of his enemy.

Gospel: Mark 9: 38-40
38 John answered him, saying: Master, we saw one casting out devils in thy name, who followeth not us, and we forbade him.
39 But Jesus said: Do not forbid him. For there is no man that doth a miracle in my name, and can soon speak ill of me.
40 For he that is not against you, is for you.
