The doctrine of the Blessed Trinity frequently has very little impact on the spiritual lives of most Christians. The Feast of the Blessed Trinity, then, is not one of the most celebrated feast days of the Church: it is not marked by such festivities as, for example, Corpus Christi or the Immaculate Conception.

Trinity Sunday, however, does play an important part in fostering our Catholic spirituality. The readings remind us that Jesus did not come into this world on His own initiative. Nor did He go through this world alone. All the gospels remind us that He was a man filled with the Holy Spirit. He was conscious of His mission: He was sent to do the Father's will and so accomplish the work of our redemption. Jesus was a perfectly self-transcendent person. His whole life was an engagement in the work of God for our salvation. His whole human life was entirely engaged in his salvific mission. This earned Him the enmity of the Jewish rulers, but that enmity did not deflect Him from His purpose in life. In Jesus we find the model for our own lives.
