Objection 19): The Joint Declaration with the Lutherans is not manifest heresy because John Paul II and Benedict XVI didn’t sign it.

Answer: The Joint Declaration with the Lutherans by itself proves that the Vatican II “popes” are non-Catholic antipopes.  The fact that John Paul II and Benedict XVI neither wrote the document nor signed it is completely irrelevant.  They both approved of it publicly numerous times, and agreed with it. 

John Paul II, Jan. 19, 2004, At a Meeting with Lutherans From Finland: “… I wish to express my gratitude for the ecumenical progress made between Catholics and Lutherans in the five years since the signing of the Joint Declaration on the Doctrine of Justification.”[1]

Benedict XVI, Address to Protestants at World Youth Day, August 19, 2005: “… the important Joint Declaration on the Doctrine of Justification (1999) …”[2]

James Smith could draw up a document denying the Immaculate Conception, and if you were to go around giving speeches about how great Smith’s document is, that would make you a manifest heretic.  The fact that you didn’t write Smith’s document or sign it means nothing; you publicly approved of it.  John Paul II and Benedict XVI publicly approved of the Joint Declaration with the Lutherans on Justification, which teaches that the worst Lutheran heresies are not condemned by the Council of Trent.  They are manifest heretics.
