The answer you’ll hear is “ecumenism” namely that Christians need to come together
But note that the onus always seems to be on Catholics to change to become more Protestant
Why isn’t the onus on Protestants to become more Catholic?
After all, the Protestants are the ones who abandoned Catholicism, not the other way around.
When a child runs away from home, the parents don’t conclude “we need to change to be more like our kid who ran away so we’ll all get along”, no the kid needs to accept he shouldn’t have left.
How much contact have you had with Protestants in the last few years?
The current cover of “Christianity Today” (a magazine founded by Billy Graham and targeted primarily to Evangelical Protestants) features a beautiful portrait of Mary, the First Christian.
In our city, many of the Evangelical churches have services featuring chant, Latin, incense,
lectio divina , recitation of the Creeds, veils worn by women, kneeling in prayer, praying with beads (not the St. Dominc Rosary we are familiar with, but one featuring the Our Father and other prayers from the Bible), and also confession (not to a priest, but to fellow believers–hey, give 'em a break! It’s a step in the right direction!)
There is controversy about this, as some Evangelicals from the more Fundamentalist churches believe that these churches are becoming “too Catholic”.
So–your wish is granted! Protestants, at least in some areas, are becoming “more Catholic!”
And if it makes you feel any better, my husband and I started attending an Ordinary Form of the Mass back in 2002 after we were kicked out of our Evangelical Protestant church (because of a lie propagated by a jealous female pastor), and we had NO CLUE what was going on, other than the Lord’s Prayer and the Bible readings, and we didn’t know ANY of the hymns sung, even though they were (and still are) from the Gather Hymnal!
So relax and stop worrying–the Catholic Church is definitely not becoming “more Protestant,” otherwise Protestants like us wouldn’t have had to make an appointment with the priest to ask him to please explain what on earth was happening in the Mass!
