After his parents' death, Erasmus was forced to live with the monks for six years. This experience did not endear the priesthood to him. After leaving the monastery he because a teacher in Paris. He later moved to England and spent most of the rest of his life living there.
He did see faith as a personal issue, one of a relationship between God and man and less of relationship based around church doctrines. He wanted people to embrace "the true spirit of the Scriptures - simplicity, naivety and humility. These, he says, are the fundamental human traits that hold the key to a happy life." (p97 philosophy book)
He worked on a translation of the New Testament, wrote several books, pointed out the folly of people and the need to have a personal faith in God. He walked a hard line of wanting to stay loyal to the Roman Church, and yet seeing truth in much said by reformers. He couldn't commit to either fully... at his death he did not ask for last rites, which spoke to understanding of the need for personal faith above church doctrine.
Be mindful of who you are.
