Aertnys - Theologia Moralis

Verumtamen Ecclesiae orationes apud Deum magnam vim habent ad impetrandum; diligit enim eam tamquam sponsam.

Never the less, the prayers of the Church have great power with God of obtaining favor, whom he loves as his spouse.

- Aertnys, Josef and Damen, C. A. Theologia Moralis: Secundum Doctrinam Sancti Alfonsi de Ligorio Doctor Ecclesiae, vol. 2. (Marietti, 1950), 35.

The special efficacy of the prayer of the Church is the basis of the power of sacramentals and therefore blessings. Here, Aertnys cites Thomas (n. 90-93 S. Thom. 3. qu. 87. a. 3.)

It will be necessary to establish the efficacy of the prayer of the church to be able to speak of the nature of blessings.
