Given your mentor’s background, even though she does not have the acedmic degree, it sounds like she has the experience. That’s a spritual director. Catherine of Siena was a lay woman, never had a degree. Francis of Assisi was a lay man, never had a degree. Elizabeth Ann Seton was a Sister, never had a degree. The Cure de Ars was a priest, never had a degree in Mystical Theology. These people have an insight into the soul that is just as good as a degree or even better.
A confessor is not a spiritual director. Confession is not mean to be used as Spiritual Direciton. However, it can be, if the priest is trained in spiritual direction and if it’s done when there is time for intercourse between the individual and the priest. The usual Satuday line is not the time for Spiritual Direction. If you go to my parish we have three priests hearing confessions every Saturday and there is a line almost an hour long for each priest. Only one of our priests is trained in spiritual direction. The others always refer you to either him or to one of our Lay Brothers who is a Mystical Theologian or two of our Secular Franciscans who were appointed by the Church to be Spiritual Directors.
That being said, I would never discourage anyone from bringing up the spiritual llife in the confessional. It’s up to the priest to be honest and say whether he knows what you’re talking about or is out of his league. They usually do well in the area of virtue. It’s in the area of prayer and ascetisism that they have little training.
I do believe that everyone should have a good spritual director. There is more to the Christian life than just staying away from sin. We have to move forward in the area of contemplation, ascetisism, meditation on the virtues, conemplation of the reality of God, submission to obedience, detachment from things and persons, and knowledge of grace. Otherwise, we remain at the beginning stage, as St. Teresa of Avila pointed out.
Fraternally,
