An especially happy day for me, as this is the titular feast day for my parish.

Here is a beautiful prayer by the Saint from saints.sqpn.com:

Prayer for the Gifts to Seek God and Live in Him

Father, in your goodness grant me the intellect to comprehend you, the perception to discern you, and the reason to appreciate you. In your kindness endow me with the diligence to look for you, the wisdom to discover you, and the spirit to apprehend you. In your graciousness bestow on me a heart to contemplate you, ears to hear you, eyes to see you, and a tongue to speak of you. In your mercy confer on me a conversation pleasing to you, the patience to wait for you, and the perseverance to long for you. Grant me a perfect end – your holy presence. Amen.
