If you have evidence of Dylan renouncing his faith in Christ, please present it.
And could you please explain your 'joooooos' comment. At face value, it comes across as an anti-Semitic slur.
The Jooooooooos comments were to thumb our (glorious) Jewish noses at those who accuse us of being too involved in science, finance, art, what have you.
Re his faith, decidedly Jewish. By the way, in Judaism, a Jew cannot renounce his or her Judaism. Dibs on his true soul forever, as it were.
