Wheat and Tares is one of the most constantly misunderstood and misrepresented parables in the New Testament.

A tare is a weed that, before it is fully grown, appears virtually identical to wheat. Sowing tares among the wheat would mean that short of individually examining every single plant, there is no reasonable way to discern between the two.

While the presence of tares reduces the available space and resources that wheat can use and can reduce a crop, wholesale attempts at removing the tares early is more than likely to result in a lot of good wheat also being removed. Ultimately it's more productive to just wait and separate them at harvest.

The parable was never about people not good enough, people who fall away, or people who are lead astray. Tares are tares from the get-go, wheat doesn't turn into tares, nor do tares turn into wheat.

The point of the parable isn't that the good will be divided from the bad. The point is that the bad are already bad, but aren't going to be cut off before they have a chance to show what they really are.

It is an argument AGAINST cutting off people from Christ, trying to pre-determine someones fate, worthiness, righteousness or destination. The 'bad' will show themselves, they don't need to be hunted or guarded against.

It is also trying to make the point that those who are not good appear the same as those who are good, and it's only at the end they show themselves for what they are. While modern Christianity likes to take this to mean they have to be on guard from 'evil' all the time and that everyone is potentially an enemy; like virtually every single other one of Christs teachings, taken in context, has a very different meaning.

When you consider who was against him at the time, what sort of teachings and ideas he came to work against, you can see pretty easily he's not talking about some random bad people. He's clearly talking about the priests who appear to be righteous, claim they are the way, and have the keys, but are ultimately false. There was debate among the discipleship on whether or not gentiles should be tought and given the gospel, or if it should remain something that was singularly jewish as it originated. In this context, too (given that parables often have many implications), Christ is basically saying "don't judge anyone now. Let all come, and at the end, they will have judged themselves."

Which, you might notice, is directly contradictory to the excommunication, disfellowship and censorship happy leadership of this specific church.

I mean just step back a second and think about the context of this children of same-sex relationship doctrine.

Christ said "Let the little children come to me and do not try to stop them, for the kingdom of heaven belongs to such as these."

The church is saying "We'll get to you children when you sufficiently adhere to what we teach, and then and only then, will we allow you into our heaven".

That's pretty much all anyone anywhere needs to know about whether or not this church is 'true'.
