HT, are you and our your W greek orthodox? My experience, unless that's changed, is it is very old testament...
Good stuff of course, but a lot of fire and brimstone stuff that for non-initiates, can be quite harsh and overwhelming...
I'm RC though, so not far off. Our church and RC in general has moved to a more new testament position over the last 30 years or so. Much more tolerance...
Anyhow, just saying and asking...
As far as the kids aggression, and rough play including things like pulling hair... yeah... not so good... IMHO...
