There are also those who do not know, yet are ready to learn from those who know, according to their ability and receptivity. The knowledge of some is ascribed to all because of the universal and inseparable unity.
The ignorance of some is passed over in silence. It will be replaced by knowledge that does not come from outside, but abides within the Church.
The words, "you have no need that anyone teach you," must be understood in relation to those false teachers who left the Church, or who were never in her. They strive to bring into the Church their falsely named truth and their falsely named reason.
The holy Apostle warns against them when he says: you have no need that anyone, meaning someone coming from outside, a stranger to Christ's fold, should teach you. In the same way he warned above against the antichrists.
According to him, "they went out from us, but they were not of us" (v. 19). Members of Christ's Church must certainly beware not of their own teachers, but of these outsiders and impious men.
After this, the "anointing from the Holy One" should not be understood as the anointing proper to each believer individually, given in the second mystery, chrismation. Rather, it means the Holy Spirit who abides in the Church and instructs her pastors to rightly divide the word of truth.
If one understood here the anointing given to each person separately, it would follow that it had already taught everyone. Then there would be no distinction between children and fathers.
But if one understands the Spirit dwelling in the whole fullness of the Church, then it is clear that, while teaching the whole Church, He diversifies His gifts among her individual members. He divides operations and ministries (1 Cor 12:4-11).
