David. R. Goodworth explores saying 1.6R/Th14 from his book 'The Gospel of Thomas: Evolution'.

“If you fast you will bring a sin for yourselves. If you pray you will be condemned and if you give alms, you will cause harm to your spirits.

If you go into any land and walk in its regions, if they should receive you, eat what they eat and heal the sick among them. For that which goes into your mouth will not defile you, rather that which comes out of your mouth, is that which will defile you.”
