On the Holy Spirit; name; four things to be proved
CHAPTER TWENTY-THREE continued. On the Holy Spirit.
The Holy Spirit is the third person in the most holy Trinity, who emanates from the Father, is sent by the Son, and proceeds from both as distinct according to hypostasis. Spirit signifies (1) properly and adequately a being most simple and subtle in first act and essence, but in second act and efficacy most active. By singular property it is attributed to the hypostatic virtue, or third person which is in God, and that not rarely with the addition Spirit of Elohim, Spirit of the Lord, Holy Spirit — Genesis 1:2; Isaiah 11:2; 63:10; Matthew 12:28.
II. But concerning the Holy Spirit four things chiefly are to be proved: (1) that He truly is a person; (2) that He is an infinite person, or true God; (3) that He is a person proceeding from Father and Son; (4) that according to hypostasis He is distinguished from Father and Son.
Latin
CAPUT VIGESIMUM TERTIUM, De Spiritu sancto. Spiritus sanctus est tertia persona in sacrosancta Trinitate, quae a Patre emanat, a Filio mittitur, ab utroque secundum hypostasin distincta procedit. Spiritus significat 1. proprie et adaequate ens actu primo et essentia simplicissimum et subtilissimum, actu vero secundo et efficacia maxime activum. Singulari proprietate attribuitur virtuti hypostaticae, seu tertiae personae quae in Deo est, idque non raro cum additamento Spiritus Elohim, Spiritus Domini, Spiritus sanctus — Gen. I.2; Isa. XI.2; LXIII.10; Matth. XII.28. II. Sunt autem de Spiritu sancto quatuor potissimum probanda: 1. Revera personam esse. 2. Esse personam infinitam, seu verum Deum. 3. Esse personam a Patre et Filio procedentem. 4. Secundum hypostasin a Patre et Filio distingui.
