Saint Luke is an evangelist. That is, he wrote one of the four Gospels in the Bible. That is, he was a person who shared and spread the message of Jesus.
Jesus himself is also an evangelist. He shares and spreads the message of God. In Luke 4, Jesus takes up the scroll and reads from Isaiah 61:
The Spirit of the Lord is upon me, because he has anointed me to bring good news to the poor. He has sent me to proclaim release to the captives and recovery of sight to the blind, to let the oppressed go free, to proclaim the year of the Lord’s favor.
In the Old Testament, God speaks through the prophet Isaiah to give us that promise. In Jesus Christ, takes those words, those promises and speaks them, lives them and acts them out. Jesus not only spreads the message of God, he is the message of God. As latter-day prophet Marshall McLuhan put it, “the medium is the message.”
So what does Luke say about Jesus, about the message that this person embodies? Luke’s gospel marks the reality and activity of the Holy Spirit in the everyday world, especially in acts of prayer, acts of healing and in acts of loving service. Luke shows us Jesus, the message of a God, who lives and acts in us. In 1980, Archbishop Oscar Romero put it like this:
God’s best microphone is Christ,
and Christ’s best microphone is the church,
and the church is all of you.
let each one of you, in your own job, in your own vocation –
nun, married person, bishop, priest,
high school or university student,
day laborer, wage earner, market woman –
each one in your own place live the faith intensely and feel that in your surroundings
you are a true microphone of God our Lord.
