OK, let's look at the big picture. First exhibit, Matthew 5:27-30
"You have heard that it was said, `You shall not commit adultery.' But I say to you that every one who looks at a woman lustfully has already committed adultery with her in his heart. 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. And if your right hand causes you to sin, cut it off and throw it away; it is better that you lose one of your members than that your whole body go into hell.
Let's be reasonable: such things have not gone on in mainstream Christianity. That's because we know our Lord was speaking in what is called 'hyperbole.' Otherwise, we'd all be blind double-amputees.
Here is another example, taken from John 8:1-11:
But Jesus went to the Mount of Olives. Early in the morning he came again to the temple; all the people came to him, and he sat down and taught them. The scribes and the Pharisees brought a woman who had been caught in adultery, and placing her in the midst they said to him, "Teacher, this woman has been caught in the act of adultery. Now in the law Moses commanded us to stone such. What do you say about her?" This they said to test him, that they might have some charge to bring against him. Jesus bent down and wrote with his finger on the ground. And as they continued to ask him, he stood up and said to them, "Let him who is without sin among you be the first to throw a stone at her."
And once more he bent down and wrote with his finger on the ground. But when they heard it, they went away, one by one, beginning with the eldest, and Jesus was left alone with the woman standing before him.
Jesus looked up and said to her, "Woman, where are they? Has no one condemned you?" She said, "No one, Lord." And Jesus said, "Neither do I condemn you; go, and do not sin again."
Was our Lord expecting to never commit another sin again? No, He meant not to sin in that way or some other grave sin.
Here's another fun one from Matthew 5:28:
You, therefore, must be perfect, as your heavenly Father is perfect.
Wow, He said 'must be perfect!' Anyone around here think he or she is perfect? How about close to perfect?
In fact, Orthodoxy is guilty saying that man can be eternally perfected but never be perfect because only God is perfect and since His perfection is eternal and boundless, we are eternally perfected without attaining it.
If you really examine the passage, you see that our Lord is addressing the Pharisees and the rulers of the synagogues who do not serve the people [Matthew 23:1-12]:
Then said Jesus to the crowds and to his disciples, "The scribes and the Pharisees sit on Moses' seat; so practice and observe whatever they tell you, but not what they do; for they preach, but do not practice. They bind heavy burdens, hard to bear, and lay them on men's shoulders; but they themselves will not move them with their
finger. They do all their deeds to be seen by men; for they make their phylacteries broad and their fringes long, and they love the place of honor at feasts and the best seats in the synagogues, and salutations in the market places, and being called rabbi by men. But you are not to be called rabbi, for you have one teacher, and you are all brethren. And call no man your father on earth, for you have one Father, who is in heaven. Neither be called masters, for you have one master, the Christ. He who is greatest among you shall be your servant; whoever exalts himself will be humbled, and whoever humbles himself will be exalted."
If you read the entire passage, Jesus begins with addressing the problem of loving the title 'rabbi.' He warns people to be humble and to serve, not seeking after titles and appearances. We must recognize that the Holy Spirit teaches the hearts of the people and we are mere vessels, and those who preside do so because they sacrifice the most for the sake of the Church and her people.
We are not called to read without understanding, and a literalist has no understanding because the Scriptures were not written that way.
