Friends also saw Truth as demanding honest, simple speech, and a refusal to acknowledge double standards by taking oaths. George Fox wrote:

They gave me the book to swear on, and the book saith, Swear not at all: But I told them, if they could prove that after Christ Jesus and his apostles had forbidden men to swear, they had allowed it, I would swear. Thus I said, and my allegiance lies in truth and faithfulness, not in swearing, and so should all your allegiance lie, if you did well. I do not deny swearing upon some account, and own it upon others, but I deny it, because Christ and the apostle have said, I should not swear at all.
