This is why ortho doxa that has right belief is important, however there should be a way to come back.
Several curses of the law. I don't know if anybody could keep the Law and from which Jesus saved us:
"DEUT 28:15 But it shall come to pass, if you will not listen to the voice of Yahweh your God, to observe to do all his commandments and his statutes which I command you this day, that all these curses shall come on you, and overtake you.
DEUT 28:16 You shall be cursed in the city, and you shall be cursed in the field.

DEUT 28:19 You shall be cursed when you come in, and you shall be cursed when you go out.
DEUT 28:20 Yahweh will send on you cursing, confusion, and rebuke, in all that you put your hand to do, until you are destroyed, and until you perish quickly; because of the evil of your doings, by which you have forsaken me.
DEUT 28:21 Yahweh will make the pestilence cleave to you, until he has consumed you from off the land, where you go in to possess it.
DEUT 28:22 Yahweh will strike you with consumption, and with fever, and with inflammation, and with fiery heat, and with the sword, and with blight, and with mildew; and they shall pursue you until you perish.
DEUT 28:23 Your sky that is over your head shall be brass, and the earth that is under you shall be iron.
DEUT 28:24 Yahweh will make the rain of your land powder and dust: from the sky shall it come down on you, until you are destroyed.

DEUT 28:26 Your dead body shall be food to all birds of the sky, and to the animals of the earth; and there shall be none to frighten them away.
DEUT 28:27 Yahweh will strike you with the boil of Egypt, and with the tumors, and with the scurvy, and with the itch, of which you can not be healed.
DEUT 28:28 Yahweh will strike you with madness, and with blindness, and with astonishment of heart;
DEUT 28:29 and you shall grope at noonday, as the blind gropes in darkness, and you shall not prosper in your ways: and you shall be only oppressed and robbed always, and there shall be none to save you.
DEUT 28:30 You shall betroth a wife, and another man shall lie with her: you shall build a house, and you shall not dwell therein: you shall plant a vineyard, and shall not use its fruit.
DEUT 28:31 Your ox shall be slain before your eyes, and you shall not eat of it: your donkey shall be violently taken away from before your face, and shall not be restored to you: your sheep shall be given to your enemies, and you shall have none to save you.
DEUT 28:32 Your sons and your daughters shall be given to another people; and your eyes shall look, and fail with longing for them all the day: and there shall be nothing in the power of your hand.
DEUT 28:33 The fruit of your ground, and all your labors, shall a nation which you don't know eat up; and you shall be only oppressed and crushed always;
DEUT 28:34 so that you shall be mad for the sight of your eyes which you shall see.
DEUT 28:35 Yahweh will strike you in the knees, and in the legs, with a sore boil, of which you can not be healed, from the sole of your foot to the crown of your head.
DEUT 28:36 Yahweh will bring you, and your king whom you shall set over you, to a nation that you have not known, you nor your fathers; and there you shall serve other gods, wood and stone.
DEUT 28:37 You shall become an astonishment, a proverb, and a byword, among all the peoples where Yahweh shall lead you away.
DEUT 28:38 You shall carry much seed out into the field, and shall gather little in; for the locust shall consume it.

DEUT 28:40 You shall have olive trees throughout all your borders, but you shall not anoint yourself with the oil; for your olive shall cast [its fruit].
DEUT 28:41 You shall father sons and daughters, but they shall not be yours; for they shall go into captivity.
DEUT 28:42 All your trees and the fruit of your ground shall the locust possess.
Orthodox point of view, John Chrysostosm: http://www.newadvent.org/fathers/23105.htm
Ver. 3. “Yea, I testify again to every man that receives circumcision that he is a debtor to do the whole Law.”
That you may not suppose that this is spoken from ill-will , I say not to you alone, he says, but to every one who receives circumcision, that he is a debtor to do the whole Law. The parts of the Law are linked one to the other. As he who from being free has enrolled himself as a slave, no longer does what he pleases, but is bound by all the laws of slavery, so in the case of the Law, if you take upon you a small portion of it, and submit to the yoke, you draw down upon yourself its whole domination. And so it is in a worldly inheritance: he who touches no part of it, is free from all matters which are consequent on the heirship to the deceased, but if he takes a small portion, though not the whole, yet by that part he has rendered himself liable for every thing. And this occurs in the Law, not only in the way I have mentioned, but in another also, for Legal observances are linked together. For example; Circumcision has sacrifice connected with it, and the observance of days; sacrifice again has the observance both of day and of place; place has the details of endless purifications; purifications involve a perfect swarm of manifold observances. For it is unlawful for the unclean to sacrifice, to enter the holy shrines, to do any other such act. Thus the Law introduces many things even by the one commandment. If then you are circumcised, but not on the eighth day, or on the eighth day, but no sacrifice is offered, or a sacrifice is offered, but not in the prescribed place, or in the prescribed place, but not the accustomed objects, or if the accustomed objects, but thou be unclean, or if clean yet not purified by proper rules, every thing is frustrated. Wherefore he says, “that he is a debtor to the whole Law.” Fulfil not a part, but the whole, if the Law is of force; but if it be not of force, not even a part.
Ver. 4. “You are severed from Christ, you who would be justified by the Law; you are fallen away from grace.”
Having established his point, he at length declares their danger of the severest punishment. When a man recurs to the Law, which cannot save him, and falls from grace, what remains but an inexorable retribution, the Law being powerless, and grace rejecting him?
Thus having aggravated their alarm, and disquieted their mind, and shown them all the shipwreck they were about to suffer, he opens to them the haven of grace which was near at hand. This is ever his wont, and he shows that in this quarter salvation is easy and secure, subjoining the words,
How did you get the idea to be circumcised after baptism. Is there a protestant doctrine you read or why so I can tell others not do the same.
