Which traditions did the Jesuits attempt to blend to Christianity?

Answer 1

Catholic AnswerSome Jesuits (by no means all) attempted to blend Indian and Chinese traditions with Christianity in the belief that there was goodness in all human desires towards God. This caused controversy among the Jesuits and consternation in Rome.

from Encyclopedia.com:

The Jesuits' frequent acceptance of non-European rituals as a means of expressing Catholic truths further emphasized their implicit belief in the goodness of human nature. Holding that nature, human and otherwise, was not intrinsically evil, the Jesuits granted greater latitude in the performance of certain indigenous practices by converts. Nobili in India and Ricci in China allowed those indigenous rituals not perceived as injurious to the faith. Reports of native Christians wearing Brahmin designations or Chinese converts bowing before ancestor tablets left some missionaries (including some Jesuits)and theologians disturbed. They feared such practices jeopardize the efficacious action of the sacraments or could lead to synchronistic and superstitious practices.
