Most likely why there is this upcoming meeting is because a lot of Catholics are leaving the Church for the Evangelical churches that are growing there.
Among the undoubted advantages of the Evangelical and Pentecostal brethren is that their model for ministry is --- and not in a bad sense --- entrepreneurial. If a man (or woman) feels they have been given a mission by God, all he has to do is open up a storefront or a house in a mixed-use zoning neighborhood, put out a sign that says "Iglesia de Dios en Cristo en el Evangelio del Espíritu Santo de Medellín" or whatever he wants to call his holy enterprise, and ¡Mira! He's a pastor of a church.
There are huge numbers of these quick start-ups, and some of them prove viable and give rise to new constellations of churches and fellowships if franchising proves popular.
It's evidently meeting spiritual needs in otherwise pastorally-neglected places. And to my mind, it's better to have a bodega church than no church at all. God bless them. Faith needs fellowship.
