Ordinarily only a deacon, priest, or bishop is allowed to proclaim the Gospel at Mass. The United States Conference of Catholic Bishops’ Committee On Divine Worship reminds us that: "The proclamation of the Gospel is reserved to the deacon, if he is present, or to a priest" (Introduction to the Book of the Gospels, 8). An exception is made during Holy Week, when the laity may join in the reading of the Passion. But the Church stipulates that a priest, who ministers in the person of Christ, must read the words attributed to Christ. So your parish should not be dramatizing the Gospel on the Sundays of Lent—period. There is no official Church documentation to support such practice.
