This paradigm shift discusses personality and how much it shapes a denomination or church.
In many Protestant churches, particularly non-denominational or Bible churches, the influence of a singular personality on the church and its members is pretty high. Because preaching is so central to many of these communities, it figures that the experiences, characteristics and charisma of the one doing the preaching becomes the identity of the church itself. It is not uncommon for one to attend such a church solely to hear the preacher preach.
Some of these charismatic leaders become superstar televangelists like Joel Olsteen, Creflo Dollar, Kenneth Copeland, Oral Roberts, Robert Schuller, Joseph Prince, Jim & Tammy Bakker and many others who go on to establish mega-churches, mega-ministries and, to be sure, mega-corporations. Frequently, these become family dynasties that the second generation usually bungles. At any rate, the existence of the church is tied to the existence of the pastor and when the latter retires, dies, or gets caught in a sex scandal, the church and its members fade away like lilies in the field.
As far as television personalities that are Catholic and could be described as televangelists, I can only think of two: Bishop Fulton Sheen who pioneered using television to spread the Gospel from 1951-57 and Mother Angelica who started the EWTN network in the 1970’s. The former eventually became archbishop and is posthumously venerated en route to beatification; the latter was a wimple-wearing nun who recently died after a decade of health problems, and most of the shows on EWTN do not feature her; she too will likely be venerated.
Generally speaking, the Catholic Church doesn’t feature preaching as much as it features the Mass which features Jesus Christ more than anyone. The celebrant priest wears a chasuble over a number of other vestments during Mass—not to look impressive – but to “cloak” his individual identity and become more of what the church terms the alter christus (another Christ). This is why only men are ordained in the Catholic Church and why priests are suitably unmarried and celibate. That is why the congregation stands when the priest stands up during Mass—to defer and honor the Lord Jesus Christ. That is why the priest reads the Gospel passages which represent the preaching of Jesus Himself. That is why only he presides over the liturgy of the Eucharist and intones the words of the Last Supper as Jesus did (and does) at the institution of the New Covenant. And most all the words of the liturgy are pre-arranged for a three-year cycle so that any priest anywhere is doing pretty much the same thing—and it is never to be varied or personalized. No!
In addition, there is a general directive for those attending the Mass not to stand out in any way but to strive to become one in unity during the Rite. To maintain this unity, responses and gestures of the faithful are prescribed to a large degree: one should bow only with the head when receiving communion, knell after the Sanctus, stand after the great Amen, say the responsorial, pray the Our Father, kneel again after the Agnus Dei, etc., etc. —and always together. When music is performed for the Mass, there is to be no applause because it is not performance or an exhibition of talent. It is void of personality so that Jesus becomes the personality from start to finish.
