We all might do well to remember that there is more that the Church hasn’t defined about Sacred Scripture than it has defined.
A second point is that while the Church has always turned to theologians for answers to understanding Scripture more deeply, theologians do not define Church teachings; the Church does.
Theologians study Scripture, or the structure of the Church, or some other field of theology, and they try to advance the understanding of God as revealed by Christ and through the teaching of the Church. In that, there is always an element of speculation; it becomes less speculative as more theologians work on an issue, and come to some understanding and explanation of it. Many theologiand are true to the Church, and defer to its authority (Dr. Hahn is one who does), and some do not. But just because a theologian has expounded an idea doesn’t mean the Church is going to take a position on the correctness of his conclusions. In other words, within theological research, there is generally a good amount of leeway as to what is acceptable and what is not. Some of what is acceptable (i.e. not heresy) is very good, some of it (still not heretical) doesn’t amount to a hill of beans.
One other thought to keep in mind: God is neither male nor female. Revelation has shown us God as “He”, and there ismore than a bit to be learned there. Having said that, Genesis says that God created us in God’s image. If there are no aspects of the feminine in God, then woman is not created in God’s image, and that would be a direct contradiction of revealed truth. To speak of feminine aspects of God is not to commit heresy, but to struggle with what we mean when we say “God”. For example, the OT refers to God in nurturing terms of feeding, clothing, sheltering, etc.
