Professor Davey has I believe been quite cunning. Instead of presenting Bishops or the spiritual as a class he casts them and only them as individuals guaranteed invariably and automatically selected. I can see why he has done that because,as a class Lords spiritual are on a par with Lords temporal. There are automatically hundreds and hundreds of Lords temporal.
Firstly - although, I say that like it's a new point and hasn't been raised multiple times already - the 'Lords Temporal' as a definition is just those lords who aren't Lords Spiritual. They are defined by their relation to that special status group, they aren't a thing in their own right. They are, therefore, not 'on a par' with the Lords Spiritual, they are all the lords that don't have that special 'Lords Spiritual' status.
Secondly,you have obviously not picked up on the observation of invariable selection of groups to the house of Lords and we have always known that there are invariably political appointments,invariably captains of industry,finance ,academia,entertainment, sport etc.(and frankly your claim that spirituality is on a par with some of these is frankly trivialising spirituality.
There is a difference between things that tend to happen either because it makes sense (nomination of eminent scientific or business individuals), or because it's a knock-on effect of other issues (nomination of retiring politicians) and inequity that's formally built in to the system. If you want to change the make-up of the lords you can nominate different people, but that won't affect the structural bias that comes from having reserved seats for churchmen.
Personally, I think that putting 'spirituality' on even a nominally equal footing with science, industry, sport, healthcare and the military security of the country trivialises reality, but we're not justifying our own personal thinking, we're trying to establish what's an equitable representation for the nation.
I shall leave it to you to sort out the difference between invariably and automatically.
Just did that. I shall leave it to you to fail to even pretend to justify the special treatment of 'spirituality'.
Which brings us to the crux of the matter. The HoL are chosen because of expertise and experience. The moment you say that spirituality does not need the level of expertise in the HoL you are absolutely relegating spirituality to trivial proportions which only reflect a certain viewpoint.
Which doesn't address why you think spirituality needs to be treated differently. I'm not saying it doesn't need a level of expertise, I'm not relegating it in comparison to everything else. We have scientists in the Lords without needing to have a special mechanism to ensure that sufficiently capable scientists have reserved seats. We have industrialists and businesspeople in the Lords without needing to have a special mechanism to ensure that sufficiently capable business people have reserved seats. We have former service members in the Lords, we have former healthcare workers in the Lords, we have former sportsmen and sportswomen in the Lords, we have teachers, authors, charity workers and politicians, and no special mechanism for any of them to ensure that they are sufficiently capable or to ensure a suitable minimum representation.
We have Muslims, Buddhists, Sikhs, Jews and who knows, possibly some atheists and Pagans for all I know.
But only Christianity seems to need special help.
Why is Christianity - or spirituality more generally, if you want to go that way, in need of special consideration.
