JESUS' warning: "Follow a good doctrine." By Angela Bernales

Why Jesus warned us about following a "good doctrine."? He refers to a practical philosophy rather than a visionary or aloof theory. Only a variety of worldly experiences and observation can give us a mature thought. After reaching that level of understanding then our inner sense, the part of our mind that make us aware of the ethical aspect of the nature of our actions, starts working using the language of the heart and at the same time the urgency to prefer right over wrong.
When Jesus spoke to the multitude, and to his disciples, about "following a good doctrine,"he described right after what was happening in heaven to MOSES' place in the assembly. Scribes and Pharisees sat in Moses' seat and because they were using that specific place, all of them urged the people to "observe and do" without questioning anything. Jesus made the warning :"Do NOT follow your doings after their (scribes and the Pharisees)works, for they say "do" what they "do not do."
Their doctrine make them bind or tie up heavy burdens that produce or give birth to great suffering and trouble, and lay them on men's shoulders; but neither the scribes nor the Pharisees are willing to help the people to carry the burden not even with one of their fingers.
But all the work they (scribes and Pharisees) do in their "DOCTRINE," is for display to men with the only purpose in mind to collect followers that are reduced to silence simply because the multitude and disciples can be easily undermined due to the lack of understanding.
In the "Dialogues of Plato" we see the same doctrine that Jesus is talking about when in 399B.C. the seventy-year old Socrates was tried before the judges and citizens of Athens on charges of impiety and corrupting the young. He was found guilty and sentenced to death. The doctrine of the accusers and judges was exactly the same presented by Jesus in reference to the scribes and Pharisees.
Plato was present at the trial, and the "apology" is his account of Socrates defending himself. The accusers were so persuasively in their doctrine that 'their truth' was delivered eloquently duly ornamented with words and phrases, with the confidence that the targeting audience, specially the youth, were caught in the mask of their persuasion.
It sounds familiar to us and we can see that now, in our days, the same method is applied in religion, politics, and other related fields. We need to be aware of what kind of doctrine they proclaim and the best way to do it is lecturing yourself on the way of self-improvement, searching into your soul and other people the TRUTH before following what they preach.
