Słomka, Walerian (Wydawnictwo Towarzystwa Naukowego Katolickiego Uniwersytetu Lubelskiego, 1992)
The author is well aware of the ambiguity o f the concept of act and prayer. Determining the range of the concept he uses he discusses this problem in five points: 1. dismissing the value of prayer for the sake of act 2. substituting act for prayer 3. act as a prayer 4. living in tune with the principle: “Ora et labora” 5. postulating a complementary vision.
