The scribes were treated with excessive deference in Jewish society because of their education and learning. Everyone honored them because of their wisdom and intelligence. The "mere children"(napioi in Greek, really meaning babes) were Jesus' image for the uneducated and ignorant. He is saying that the gospel of grace has been disclose to and grasped by the uneducated and ignorant instead of the learned and wise. For this Jesus thanks God... The babes (napioi) are in the same state as the children (paidia). God's grace falls on them because they are negligible creatures, not because of their good qualities. They may be aware of their worthlessness, but this is not the reason revelations are given to them. Jesus expressly attributes their good fortune to the Father's good pleasure, the divine eudokia. The gifts are not determined by the slightest personal quality or virtue. They were pure liberality. Once and for all, Jesus deals the death blow to any distinction between the elite and the ordinary in the Christian community.
