Father Aquinas was one of my favorite teachers. I had him for Religion Class,("Message of Mark") which focused on the Gospel of Mark. He was very passionate about his Catholic faith and he wasn't afraid to show it. He scared me a little at first, but after awhile I grew to like him. One of my most memorable high school classes, as I learned much from this faithful servant of God. Rest in Peace Father Aquinas. I will remember you always.

Fr. Aquinas was my English teacher at Uni in 1978 and 1979. Although he was prone to spending as much time giving a sermon on morality as he would spend lecturing on grammar and literature, he was an effective teacher. A significant part of my professional life involves writing or editing the writing of others, and any success or skill I have is due in no small part to his instruction.
My condolences to his family.
