Markus 2:16

2:16 When the experts in the law ¹  and the Pharisees ²  saw that he was eating with sinners and tax collectors, they said to his disciples, “Why does he eat with tax collectors and sinners?” ³ 

Markus 3:29

3:29 But whoever blasphemes against the Holy Spirit will never be forgiven, but is guilty of an eternal sin” ⁴ 

[2:16]  ¹ tn Or “the scribes.” See the note on the phrase “experts in the law” in 1:22.

[2:16]  ² sn Pharisees were members of one of the most important and influential religious and political parties of Judaism in the time of Jesus. There were more Pharisees than Sadducees (according to Josephus, Ant. 17.2.4 [17.42] there were more than 6,000 Pharisees at about this time). Pharisees differed with Sadducees on certain doctrines and patterns of behavior. The Pharisees were strict and zealous adherents to the laws of the OT and to numerous additional traditions such as angels and bodily resurrection.

[2:16]  ³ sn The issue here is inappropriate associations. Jews were very careful about personal associations and contact as a matter of ritual cleanliness. Their question borders on an accusation that Jesus is ritually unclean.

[3:29]  ⁴ sn Is guilty of an eternal sin. This passage has troubled many people, who have wondered whether or not they have committed this eternal sin. Three things must be kept in mind: (1) the nature of the sin is to ascribe what is the obvious work of the Holy Spirit (e.g., releasing people from Satan’s power) to Satan himself; (2) it is not simply a momentary doubt or sinful attitude, but is indeed a settled condition which opposes the Spirit’s work, as typified by the religious leaders who opposed Jesus; and (3) a person who is concerned about it has probably never committed this sin, for those who commit it here (i.e., the religious leaders) are not in the least concerned about Jesus’ warning. On this last point see W. W. Wessel, “Mark,” EBC 8:645-46.
