Within this Mystery the veil that has so long shrouded the trinity has been pulled back. With the descent of the Holy Spirit we the Church welcome the appearance of the blessed and undivided Holy Trinity in it's fullness. We have a clear picture of the Father sending; through the Son the Holy Spirit; Paraclete, Advocate, Consoler, and "Spirit of truth" (John 16:13). As our Paraclete he calls us to remember the Risen and Ascended Lord: "the Holy Spirit, whom the Father will send in my name, he will teach you all things, and bring to your remembrance all that I have said to you" (John 14:26). As our Advocate The Holy Spirit teaches us Christ's truth "the Spirit of truth, who proceeds from the Father, he will bear witness to me" (John 15:26). Finally as our Consoler the Holy Spirit opens our hearts to wholly welcome the truth.
As the "other tongues" suggest the incommunicable language of the Trinity has now become a human language of prayer available to each member of the Church. St. Paul himself announces the special gift that comes with the grace of Pentecost: "When we cry 'Abba Father!' it is the Spirit himself bearing witness with our spirit that we are children of God" (Romans 8:15). When we remember that the Holy Spirit makes it possible for us to communicate with God, then we recognize the possibility of sharing that communion with others. It is through the now fulfilled and revealed love shared by the Holy Trinity we are reminded of Christ's wish "that they may be one" (John 17 :11). This plan of love, which was conceived by the Father and realized by the Son victorious over death, continually unfolds under the impulse of the Holy Spirit who leads "to all truth" (John 16:13). While contemplating this Glorious descent of the Holy Spirit we are given an occasion to thank God for his grace, and to recall that which unites us in divine truth.
