This looks like straightforward adversarial religion in medieval format ,
with an added explanation so that new Christians should not misunderstand
culled from the script of some other first century preacher!
It is clear that Jesus equates the Kingdom of Heaven with the world.
This is where the seed was sown and this is where adversity, the weeds, will be met.
This is where the good and the bad grow together and intermingle,
and separating them would involved final rejection
of one group of beloved for another.
We are not puppets, nor can all evil be eradicated by a quick blast of magical selective weed-killer,
and, over millennia, those weeds have changed into something that looks vaguely like wheat.
Humanity is, in many areas of the world, slowly adopting a moral compass.
Mankind is slowly starting to love its neighbour.
We are not the barbarians that we once were.
It is a slow process with many reversals but mankind is changing.
We can only look forward to a distant future when the evolutionary process is complete;
when the weeds of today's inequalities have all been replaced by golden wheat;
when the harvest is ready.
But this has nothing to do with medieval fairy tales of angelic workers or devilish plots.
Nor is it about hell-fire and segregation of those unworthy to sit at the mystical table of the Lamb,
for part of this parable is that the weeds had already been sown in the churches at the time of writing.
The message that Jesus preached had already been corrupted by the foolishness of his messengers;
limited by their preconceptions, time-bound vision and understanding of the world,
and by the biassed agenda of those hungry for power and significance
or hungry to cash-in on fears of an eternal time of torture.
We do need to do more than just read our Bibles. We need to take them seriously.
We need to analyse them and think through what is really being said.
Which bits are timeless (Jesus) and which are time-bound (author)?
Is it promoting love (Jesus) or discord (the divisive church) ?
Does it promote inclusion or separation,
schism or love ?
We do need to do more than just accept the leadership of our clergy.
Are they leading us towards love or discord, inclusion or separation ?
Are they leading us out to love our neighbour or closing the doors against them?
We are free people and need to take responsibility for that freedom.
In the eyes of divinity that is why we were made what we are.
