One of the rising phenomena in the Church is the number of converts.
Where once upon a time the majority of Catholics were "cradle-Catholics", there is now a significant number of converts and they are also serving in the various ministries of the Church.
It could be because of the RCIA that gave more publicity to the process of joining the Church and getting baptised.
And it is certainly a blessing as these converts also gave a new perspective to the Church.
St. Luke, whose feast day we celebrate today, was Greek convert to Christianity.
He was also a faithful companion to St. Paul when he was in captivity, and he made it a point to mention that in the 1st reading.
St. Luke went on to write the Gospel and also the Acts of the Apostles.
In those two books, he gave a perspective that appealed to those who were thinking of joining the Church and hence made it easier for them to make the decision for Christianity.
So whether we are cradle-Catholics or converts, we have a mission like that of St. Luke, and that is to present the Good News of Jesus Christ in a way that non-Christians can find it appealing and understandable.
They may not have read the Bible, but our lives of faith are the books that they will read in coming to know who Jesus is.
