Only the first and possibly the last seem legitimate to me: that is if they they are accurate quotes. . There have been all kinds of things attributed to certain popes over the centuries that have been wrong. Like the one about Leo X saying that the 'myth of Christ has served us well'. Protestants love to use this alleged quote in their attempt to show that the popes are SOS, anti-christ etc. Pastor covers how it is a fraud.
Probably the most infamous of all libels is the one attributed to Marie Antoinette--she never said 'let em eat cake'.
