哥伦布是否是一个虔诚者？如果是，他的信仰又是否始终如一？哥伦布在首航过程中搜寻黄金以及征服原住民的行为展现了哥伦布早年行为与信仰的冲突，在面对这一矛盾时，哥伦布采用了二元论的处理方式，即“上帝的归上帝，凯撒的归凯撒”。但由于他在第二与第三次航行中接连遭受挫折，所以在第四次航行前，哥伦布全身心地投入宗教研究以寻求帮助，正是在此时，哥伦布的信仰变得越来越狂热，并最终通过《预言书》这一文本表现出了他的虔诚信仰。哥伦布的精神体验不仅展示了这位发现者自身的信仰转变，也展示了15-16世纪背负着十字架前行的伊比利亚社会。

Is Columbus a pious man? If so, is his belief consistent? Columbus's search for gold and his conquest of the aborigines during his first voyage revealed the conflict between Columbus's early actions and beliefs. In the face of this contradiction, Columbus adopted a dualistic approach, that is, ”God to God, Caesar to Caesar”. But because of his successive setbacks during the second and third voyages, Columbus devoted himself to religious studies for help before the fourth voyage. It was at this time that Columbus's faith became more and more enthusiastic and finally showed his pious faith through The Libro de las profecías. Columbus's spiritual experience not only shows the discoverer's own belief transformation, but also shows the Iberian society carrying the cross in the 15th and 16th centuries.
