The two Sunday’s following Pentecost are the Solemnities of the Most Holy Trinity and the Body and The Most Holy Body and Blood of Christ. These two Sundays are intimately united, because it is in the reception of the Holy Eucharist, that we are drawn most fully, in our human nature, into the communion of the Holy Trinity. St. Faustina wrote several times in her Diary about the Holy Trinity, and usually in conjunction with reception of the Holy Eucharist. She wrote about her journey to a deeper relationship with Christ and how “His Trinitarian Being enveloped me entirely” (Diary, 1056).
On the Feast of the Ascension, 1937, she wrote:
“After Holy Communion I communed for a while with the heavenly Father. My soul was drawn into the glowing center of love. I understood that no exterior works could stand comparison with the pure love of God. ... I saw the joy of the Incarnate Word, and I was immersed in the Divine Trinity. When I came to myself, longing filled my soul, and I yearned to be united with God (Diary, 1121).”
Again, after receiving Holy Communion, she began to understand that the entire Holy Trinity came to dwell within her soul:
“Once after Holy Communion, I heard these words: You are our dwelling place. At that moment I felt in my soul the presence of the Holy Trinity, the Father, the Son, and the Holy Spirit. I felt that I was the Temple of God. I felt that I was a child of the Father. I cannot explain all this, but the Spirit understands this well (451).”
St. Faustina began her Diary by expressing her desire to know more, about the Trinty.
“On one occasion I was reflecting on the Holy Trinity, on the essence of God. I absolutely wanted to know and fathom who God is. ... In an instant my spirit was caught up into what seemed to be the next world. I saw an inaccessible light, and in this light what appeared like three sources of light that I could not understand. And out of this light came words in the form of lightning which encircled heaven and earth. Not understanding anything, I was very sad. Suddenly, from this sea of inaccessible light came our dearly beloved Savior, unutterably beautiful with His shining Wounds. And from this light there came a voice which said, Who God is in His Essence, no one will fathom, neither the mind of angels nor of man. Jesus said to me, Get to know God by contemplating His attributes. A moment later, He traced the sign of the cross with His hand and vanished (30).”
On this the feast of the Most Holy Trinity, let us ask the Holy Spirit to flood our hearts with the same desire as St. Faustina, to know and fathom who God is….
