Rom 8:1-2 seems pretty clear.

Rom 8:1 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.

Rom 8:2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.

If a minister or brother does not believe that “there is no condemnation for those who are in Christ Jesus,” he just may not be where he ought to be “in Christ Jesus.”

So, “to teach otherwise is to teach false doctrine.” If exposing false doctrine is un- Christian, then Christ was not very Christian. But of course Christ is the very definition of Christian. And no one exposes false doctrine as much as Christ exposes false doctrine. So exposing false doctrines is actually a very important part of being a true Christian. But just for the record, even the old covenant prophets dispensed with this doctrine long before Christ came along. Here it is in Ezekiel 18:

Ezekiel 18:1 The word of the LORD came unto me again, saying,

Ezekiel 18:2 What mean ye, that ye use this proverb concerning the land of Israel, saying, The fathers have eaten sour grapes, and the children’s teeth are set on edge?

Ezekiel 18:3 As I live, saith the Lord GOD, ye shall not have occasion any more to use this proverb in Israel.

So how does God now deal with “the sins of the fathers?”

Ezekiel 18:4 Behold, all souls are mine; as the soul of the father, so also the soul of the son is mine: the soul that sinneth, it shall die.

Ezekiel 18:10 If he[ anyone in Israel] beget a son that is a robber, a shedder of blood, and that doeth the like to any one of these things,

Ezekiel 18:11 And that doeth not any of those duties, but even hath eaten upon the mountains, and defiled his neighbour’s wife,

Ezekiel 18:12 Hath oppressed the poor and needy, hath spoiled by violence, hath not restored the pledge, and hath lifted up his eyes to the idols, hath committed abomination,

Ezekiel 18:13 Hath given forth upon usury, and hath taken increase: shall he then live? he shall not live: he hath done all these abominations; he shall surely die; his blood shall be upon him.

Ezekiel 18:14 Now, lo, if he beget a son, that seeth all his father’s sins which he hath done, and considereth, and doeth not such like,

Ezekiel 18:15 That hath not eaten upon the mountains, neither hath lifted up his eyes to the idols of the house of Israel, hath not defiled his neighbour’s wife,

Ezekiel 18:16 Neither hath oppressed any, hath not withholden the pledge, neither hath spoiled by violence, but hath given his bread to the hungry, and hath covered the naked with a garment,

Ezekiel 18:17 That hath taken off his hand from the poor, that hath not received usury nor increase, hath executed my judgments, hath walked in my statutes; he shall not die for the iniquity of his father, he shall surely live.

Combine all that with Rom 8:2, and you have two scriptural witnesses that every man is held accountable for his own sins. God says plainly, ” He shall not die for the iniquity of his father…”
