I am a diocesan priest in the parish of Cyrill and Method in the Archdiocese of Vienna, and a teacher at the I've added Br. Thomas's description of Seven Principles of the Spiritual Life to the website. The principles, based on the teaching of St. Thomas Aquinas and St. Therese of Lisieux, are the following:
1. To keep God in mind at all times.
2. To trust in God as much as possible.
3. To do all things for the love of God.
4. Not to trust in oneself.
5. Not to seek oneself.
6. To do all things with joy.
7. To be as energetic as possible.
The sixth and seventh principles may be a bit of a surprise. Is it even in our power to do things with joy? What does "energy" have to do with spiritual life? Yet St. Paul tells us to "Rejoice in the Lord always" (Phil 4:4), and St. Therese says that energy "is the most necessary virtue; with energy one can easily reach the height of perfection" (LT 178). These and the other principles are explained at greater length in the article. Comments are welcome!
