John 15:26-16:4
The Spirit of truth will be my witness

Jesus said to his disciples:
‘When the Advocate comes,
whom I shall send to you from the Father,
the Spirit of truth who issues from the Father,
he will be my witness.
And you too will be witnesses,
because you have been with me from the outset.
‘I have told you all this that your faith may not be shaken.
They will expel you from the synagogues,
and indeed the hour is coming
when anyone who kills you
will think he is doing a holy duty for God.
They will do these things
because they have never known
either the Father or myself.
But I have told you all this,
so that when the time for it comes
you may remember that I told you.’


Acts 16:11-15
The Lord opened Lydia’s heart to accept what Paul was saying
Sailing from Troas we made a straight run for Samothrace; the next day for Neapolis, and from there for Philippi, a Roman colony and the principal city of that particular district of Macedonia. After a few days in this city we went along the river outside the gates as it was the sabbath and this was a customary place for prayer. We sat down and preached to the women who had come to the meeting. One of these women was called Lydia, a devout woman from the town of Thyatira who was in the purple-dye trade. She listened to us, and the Lord opened her heart to accept what Paul was saying. After she and her household had been baptised she sent us an invitation: ‘If you really think me a true believer in the Lord,’ she said ‘come and stay with us’; and she would take no refusal.


Psalm 149:1-6,9
The Lord takes delight in his people.

Sing a new song to the Lord,
his praise in the assembly of the faithful.
Let Israel rejoice in its Maker,
let Zion’s sons exult in their king.
The Lord takes delight in his people.
Let them praise his name with dancing
and make music with timbrel and harp.
For the Lord takes delight in his people.
He crowns the poor with salvation.
The Lord takes delight in his people.
Let the faithful rejoice in their glory,
shout for joy and take their rest.
Let the praise of God be on their lips:
this honour is for all his faithful.
The Lord takes delight in his people.

The Father and the Son revealed by the Spirit

243 Before his Passover, Jesus announced the sending of “another Paraclete” (Advocate), the Holy Spirit. At work since creation, having previously “spoken through the prophets”, the Spirit will now be with and in the disciples, to teach them and guide them “into all the truth”. The Holy Spirit is thus revealed as another divine person with Jesus and the Father.

244 The eternal origin of the Holy Spirit is revealed in his mission in time. The Spirit is sent to the apostles and to the Church both by the Father in the name of the Son, and by the Son in person, once he had returned to the Father. The sending of the person of the Spirit after Jesus’ glorification reveals in its fullness the mystery of the Holy Trinity.

245 The apostolic faith concerning the Spirit was confessed by the second ecumenical council at Constantinople (381): “We believe in the Holy Spirit, the Lord and giver of life, who proceeds from the Father.” By this confession, the Church recognizes the Father as “the source and origin of the whole divinity”. But the eternal origin of the Spirit is not unconnected with the Son’s origin: “The Holy Spirit, the third person of the Trinity, is God, one and equal with the Father and the Son, of the same substance and also of the same nature. . . Yet he is not called the Spirit of the Father alone,. . . but the Spirit of both the Father and the Son.” The Creed of the Church from the Council of Constantinople confesses: “With the Father and the Son, he is worshipped and glorified.”

246 The Latin tradition of the Creed confesses that the Spirit “proceeds from the Father and the Son (filioque)”. The Council of Florence in 1438 explains: “The Holy Spirit is eternally from Father and Son; He has his nature and subsistence at once (simul) from the Father and the Son. He proceeds eternally from both as from one principle and through one spiration. . . . And, since the Father has through generation given to the only-begotten Son everything that belongs to the Father, except being Father, the Son has also eternally from the Father, from whom he is eternally born, that the Holy Spirit proceeds from the Son.”

247 The affirmation of the filioque does not appear in the Creed confessed in 381 at Constantinople. But Pope St. Leo I, following an ancient Latin and Alexandrian tradition, had already confessed it dogmatically in 447, even before Rome, in 451 at the Council of Chalcedon, came to recognize and receive the Symbol of 381. The use of this formula in the Creed was gradually admitted into the Latin liturgy (between the eighth and eleventh centuries). The introduction of the filioque into the Niceno-Constantinopolitan Creed by the Latin liturgy constitutes moreover, even today, a point of disagreement with the Orthodox Churches.
248 At the outset the Eastern tradition expresses the Father’s character as first origin of the Spirit. By confessing the Spirit as he “who proceeds from the Father”, it affirms that he comes from the Father through the Son. The Western tradition expresses first the consubstantial communion between Father and Son, by saying that the Spirit proceeds from the Father and the Son (filioque). It says this, “legitimately and with good reason”, for the eternal order of the divine persons in their consubstantial communion implies that the Father, as “the principle without principle”, is the first origin of the Spirit, but also that as Father of the only Son, he is, with the Son, the single principle from which the Holy Spirit proceeds. This legitimate complementarity, provided it does not become rigid, does not affect the identity of faith in the reality of the same mystery confessed.
