If the Catholic Church as a group were over the centuries following Jesus and the Holy Spirit closely instead of blindly following the ways of men there would have been little incentive or willingness or need to come out of her and re-establish.
So the Reformers supposedly came out of her, but from what I can see they also often moved blindly and sometimes even more deeply into the ways of men.
Both Catholics and Reformers made mistakes but the whole mess was started by people centuries earlier than the Reformation and snowballed into and through deluded leaders and followers who had lost their first love [if ever they had that right "first love"]. Many or even most of those who left the Catholic fold did not find that love and so we have... something similar to Noah's time or similar to Sodom and Gomorrah's time? Why are people as a whole so far away from Eden before sin in spite of the sacrifice of Jesus for us? Help us dear Lord!
Jeroboam, called by the prophet of God went his own way and molded golden calves to worship and false priests to minister, but Rehoboam opened the door by following his flesh rather than God. Two wrongs don't make a right.
Now, we, all of us, should be leaving that unchangeable past and moving toward the Light which Jesus is. God still draws to Him those who are hungry and thirsty for His righteousness in order to fill them. Catholics and Protestants and others are invited. But... unfortunately I anticipate more conflict rather than less because so many still continue to say, "We are right and they are wrong". When we put our church or leadership or worldly things first, we are wrong no matter what church affiliation we have...
"But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you." Matt 6:33
so we are supposed to accept that Jesus's prayer go unanswered but that those of yourself and others
be answered that you are right now that the Catholic Church is wrong and has failed - be reasonable and come back home - twinc
