The same way we are to judge (John 7:24) anyone who claims to be a follower of the Saviour of the World:

You will forgive me for taking liberties with the Word but I do so only to illustrate a point: important though Torah is, it was never designed to be used to hate people or erect walls of partition between believers. Sometimes when I am talking to Messianics (and remember, I am one myself) I often feel the need to quote Yah'shua (Jesus) who said:

I guarantee that there isn't a single Messianic who is keeping the Law (Torah) and yet they are quick to condemn all those who do not, even to consigning them to hell. Such a course, I venture to suggest, is shere spiritual folly.

In the New Covenant we are to be Messiah-centric or Christ-centric, not Torah-centric. Obedience to Torah is supposed to flow out of our love, devotion and committment to Yah'shua (Jesus), not the other way round. Only when we have unreservedly given ourselves to the Messiah (Christ) are we to then start measuring our discipleship by a comparison with Yahweh's Torah (Law). And then we should be very careful how we judge others who are failing to be observant for by the judgment we judge, shall we also be judged (Mt.7:2). As Messianics, our commission is, having led souls to the Messiah (Christ), to teach people what His requirements for holy living are and then leave them to respond or not. We cannot force them.

It is a different matter if a believer voluntarily joins himself to your local congregation and then flouts the rules of that congregation. And whilst Yah'shua (Jesus) taught that every statute of Torah is important, even the very least (Mt.5:19), there is a difference between those statutes whose breaking excludes us from the Kingdom and therefore salvation, and those which simply cause us to occupy a lower place within the Kingdom:

When some Messianics make no distinction between these two different categories of sin, and curse (which is what they are effectively doing) believers out of the Kingdom of God for mispronouncing or spelling Deity (for example), they are guilty of a grave sin themselves.

There is another point I want to make. Teaching Torah is right and proper, but there are always two ways to teach - a right way and a wrong way. If you try to force the Kingdom down someone's throat in an aggressive and unloving manner, it doesn't matter how accurate your theology may be, because you will not possess the Spirit of Messiah (Christ) and the effect of your witness will be (quite naturally) to drive people away. Yah'shua (Jesus) said that the invitation to His Kingdom was by attraction, not compulsion:

The pull is a natural one and does not signify beating with a rod or a whip. And so when Messianics come breathing the fire of damnation on those who say the word "Jesus" and accuse them of being pagan Zeus-worshippers, they demonstrate a spirit that is utterly alien to the New Covenant, and reminds us more of the severity of the Old Covenant than the grace of the New. For in truth these people, whilst they acknowledge Yah'shua (Jesus) as their Messiah with their lips, are far from Him in their hearts (Is.29:13), and that because they were never born again, having never tasted the sweet fruit of redeeming love. And that true Ruach (Spirit) many, many Protestants most certainly have been touched by, which they demonstrate in the way they treat other people.

I have no time for the arrogant and vicious finger-pointers and accusers, for such is the spirit of haSatan (the Adversary) who is the "accuser of the brethren" (Rev.12:10). We are all in need of correction, some more than others, but there is a right way to administer that correction and a wrong way. The right way is humility and gentleness mingled with firmness. And the wrong way can have the catastrophic effect of driving the saved out of the Kingdom and to eternal destruction. Woe unto any man who is responsible for such!
