In the book Crossing the Threshold of Hope, Pope Saint John Paul II said:
“The Second Vatican Council made great strides forward with regard to both Marian doctrine and devotion. It is impossible to include here in its entirety the marvelous eighth chapter of the Dogmatic Constitution on the Church Lumen Gentium, but it should be done. When I participated in the Council, I found reflected in this chapter all my earlier youthful experiences, as well as those special bonds which continue to unite me to the Mother of God in ever new ways.”
The following is the last paragraph of Lumen Gentium’s chapter 8:
It gives great joy and comfort to this holy and general Synod that even among the separated brethren there are some who give due honor to the Mother of our Lord and Savior, especially among the Orientals, who with devout mind and fervent impulse give honor to the Mother of God, ever virgin. The entire body of the faithful pours forth instant supplications to the Mother of God and Mother of men that she, who aided the beginnings of the Church by her prayers, may now, exalted as she is above all the angels and saints, intercede before her Son in the fellowship of all the saints, until all families of people, whether they are honored with the title of Christian or whether they still do not know the Savior, may be happily gathered together in peace and harmony into one people of God, for the glory of the Most Holy and Undivided Trinity.
