I think that would be in keeping with the teachings of Jesus and the Apostles.
Today's readings included the witness of Peter: Acts 10:34-43
where he relates Jesus' marching orders,
42 He commanded us to preach to the people and to testify that he is the one ordained by God as judge of the living and the dead.
43 All the prophets testify about him that everyone who believes in him receives forgiveness of sins through his name.
Why make it anymore diffcult than that?
"The real fasting of the preacher is not from food, but rather from eloquence, from impressiveness, and exquisite diction... from everything that might hinder the Gospel of God being presented."
From "My Utmost for His Highest" by Oswald Chambers
