Without Jesus we don't know much about the mystery of God. The mystery of God is a paradoxical mystery, which is beyond human comprehension. We know as much about the mystery of God as Jesus wanted to tell us. Only through Jesus, do we know something about the mystery of the three persons in the one God. God eternally exists as Father, Son and the Holy Spirit all due equal, worship and all eternal.
Through the Annunciation, Mary probably was the first human person formally to know the name of the second person of God, Jesus. She was blessed to be the Mother of the Lord, Jesus. We are her children. We become children of God at our own baptism. We welcome Jesus into our minds and hearts when we receive the sacraments. In that sense, we become Christ- bearers. Through Jesus we know God as His Father. The Holy Family went to the Temple for the feast of the Passover. After the feast Joseph and Mary went home alone, Jesus stayed behind. When Mary found Jesus, who was talking to the leaders of the Temple; Mary told Jesus how Joseph and she were worried about Him. Jesus replied, 'Did you not know that I must be busy with my Father's affairs?' (Lk 2,49). Throughout His public life He always referred to God as His Father and His opponents charged Him with blasphemy for calling God His Father.
On the cross, Jesus talked to God the Father in numerous time. It was not a normal conversation, but it was God speaking to God. St Luke reported that in his agony, Jesus asked the Father to show mercy to those who showed him no mercy. 'Father, forgive them; they do not know what they are doing' (Lk 23, 34). This saying reveals that God's love is stronger and more powerful than the sin of those who murdered God's only Son. Again Jesus said: 'Father, into your hands I commit my spirit' Lk 23,46 The last words Jesus said on the cross to the Father, revealed the strong bond between Jesus and the Father. Nothing could break this bond, even in His utmost agony and confronted by terrible inhuman torture, the bond between the Father and the Son was not weakened but rather grew stronger.
Jesus revealed to us the third person of God, the Holy Spirit. At his Baptism there was the voice of the Father and the Spirit descending like a dove (Mt 3,13-17). In the 'Farewell discourses' (Jn 14,16) Jesus promised to send the Holy Spirit, or the Paraclete, the Spirit of truth, to guide, remind and to be with us forever. 'the Advocate, the Holy spirit, whom the Father will send in my name, will teach you everything and remind you of all I have said to you (Jn 14,26)'.
The Spirit will sanctify our lives; the Spirit will help us to pray and rephrase our prayers to the language that is acceptable to God, and the Spirit will help us to grow into holiness of God. Let us render our prayer of thanksgiving to one God in the persons of God the Father, God the Son and God the Spirit.
