29 If your right eye makes you stumble, tear it out and throw it from you; for it is better for you to lose one of the parts of your body, than for your whole body to be thrown into hell. 30 If your right hand makes you stumble, cut it off and throw it from you; for it is better for you to lose one of the parts of your body, than for your whole body to go into hell.
Catholic Answers says:
Christ used hyperbole often, for example when he declared, “If your right eye causes you to sin, pluck it out and throw it away; it is better that you lose one of your members than that your whole body be thrown into hell” (Matt. 5:29, cf. 18:9; Mark 9:47). Christ certainly did not intend this to be applied literally, for otherwise all Christians would be blind amputees! (cf. 1 John 1:8; 1 Tim. 1:15). We are all subject to “the lust of the flesh and the lust of the eyes and the pride of life” (1 John 2:16).

Tim Staples says it isn’t hyperbole. Listen here.Tim says if your eye or hand offend, cut the eye out and cut the hand off “because I’m gonna get a new one when I get to heaven…”
For all of Rome’s protests and her insistence upon the need to submit to the ‘unanimous consent’ of the fathers, as well as her own official definitive meanings of holy Scripture, there are no specific infallible interpretations to which anyone can point! Dogmatic assertions do not make for proof. At the end of the day, no matter how often the claim is made, it is still nothing more than a claim, because Roman apologists cannot produce the actual rule for which they argue.
