Modern Theology is correct and 2 Millenia of Church teaching false?

Some of the latest discussions I've been involved with have highlighted the obvious truth that not compromising one's faith is almost nearly a sin. I appreciate good honest literature on any given subject and that doesn't exclude my beliefs as a Catholic. If I want to learn about my faith for example, I will read an engaging book that unfolds the beauty and splendor of the Church. That doesn't include theologians such as Richard Gaillardetz, recently recommended to me, who claims that "the Congregation for the Doctrine of the Faith has not clearly established the infallibile nature of the ban on women’s ordination," and who gave a speech to the dissenting group "Call to Action" in 2008. http://en.wikipedia.org/wiki/Richard_Gaillardetz.

Call to Action is an organization that belittles celibate clergy, promotes "liberation theology", condones woman's ordination and undermines Church authority in her magisterium. Therefore, Call to Action isn't Catholic at all and Richard Gaillardetz is just another of the many theologians who betray their consciences by discarding the Church in favor of something novel.

The modern theologians who dissent from the Church claim "we only want peaceful dialogue". I believe that is a dishonest way of furthering their agenda to create another religion in the Church from within. They despise the all male priesthood and are filled with contempt for those in a higher authority, especially our Pope. Catholics who are serious about their faith refuse to bite the bate, and I am proudly guilty of being among them. What we need is another G.K Chesterton and Hilaire Belloc to set the record straight. These were true Catholic intellectuals who were the greatest thinkers of their time who cast an enormous shadow on today's "modern theolgians"
