The role of the Church is to bring the "fish" into the boat, from the sea, to the stability and salvation of the Church. Christ made the Apostles "fishers of men".
Unfortunately after Vatican II...the clergymen changed, the Church did not change because She cannot change.
After Vatican II, the Conciliar Church "Newchurch" accepted the world, because they wanted to be accepted by the world.
Now the Leaders of the New-Society (SSPX) accept the Newchurch, because they want to be accepted by the Newchurch.
History repeats itself!
