Since I was a young child

I knew that I wanted to be a teacher.  When I met the Dominican Sisters of Mission San Jose, quite by accident in my senior year of high school, I knew that God was up to something that would change everything.  I am blessed to belong to a congregation of Dominican women whose passion for education nurtured and disciplined my gifts for ministry.  After 15 years of teaching chemistry, biology, and religion, my sisters asked me to pursue a doctorate in theology.  Their confidence awakened me to a certain “theological passion” that seemingly under-girds all of my teaching and preaching.

The same delight

that overtakes me in the “teachable moment”, meets me in study and the intensive labor of “doing theology”; it is, in a sense, experiencing something you know you were born to do.  My heart belongs to the church in the fullness of its wonderful, frustrating, demanding and heartbreaking sacramental sojourn into the Reign of God.  Fundamentally, it is the privilege of walking with Jesus and wanting to be, in some small way, a part of the difference that he continues to effect in this world that orders my theological and religious vocation.

I am grateful

to be serving at Aquinas Institute of Theology.  Teaching and engaging in the ministry of formation for the Vocare Center has only deepened my appreciation of the livingness of the Spirit:  quickening the “sense of the faithful” and stirring new expressions of gospel fidelity among us.
