But only your family can authoritatively interpret it. Similarly, only the Church can authoritatively interpret her Book, the Bible. But that's why He sent the Spirit to guide His Church. And so it has continued for almost two thousand years. Christian fundamentalists, for all the honor they give God's Word, have strayed in their understanding of the Good News because they are cut off from the ancient, living faith of the Church, which is needed to interpret the Scriptures.
Many fundamentalists are well intentioned and receive much support from their faith.
But most, if not all, are either openly or subtly hostile towards the Catholic Church. Some simply do not understand our sense of church history and authority, the community of saints and the sacraments. Others harbor deep traditional animosities towards the Church, identifying Her with the Antichrist. Tolerance of other religious heritages, and respect for every person's freedom and obligation before God to follow his or her own conscience, do not tend to be strengths of fundamentalist groups. They can be quite narrow-minded and judgmental.
