Within 20 to 25 years, the Catholic Church will become more like it was in the immediate post-World War II era. Seminarians are predominantly conservative, and the liberals in clerical collars will age out. The Orthodox churches have a good future as well and lack the taint of liberalism that still hangs around many Catholic parishes and diocesan offices.
The mainline Protestant denominations will become real estate holding companies by 2050, as dioceses, districts, and presbyteries close congregations as the members die out. The evangelical churches seem stuck for the most part in seeker sensitive, theologically vapid mode, which appeals to Boomers and Gen. X, but is losing ground with Millennials and Gen. Z. The Southern Baptist Convention, independent Bible churches, and Churches of Christ have been losing ground over the last 10 years. Unfortunately, the leaders of megachurches and their smaller cousins are doubling down on a liturgy of bad rock music and Ted Talks. Like the mainline churches doubling down on anti-Biblical positions on social issues though retaining the older Protestant worship styles, the majority of evangelical churches are making different, yet equally destructive decisions that will lead to their decline.
The last two Popes have been complete disasters. The Catholic Church is dead now for many people.
