This book is, as you probably inferred from the title, a complete collection of the works of the 17th-century poet George Herbert. I've been reading this very slowly for the past four years, having been gifted it by my second-eldest brother when he was very concerned about me (as I was having a psychotic episode at the time) and thought some archaic Christian poetry would break through to me, which it *kind of* did - I heavily annotated the first thirty or so pages of it in purple biro, emerged from the psychotic episode (after about a week) and then finished reading it bit by gratitude-debt bit in the time since then. It's a hard book to binge, being 17th-century poetry and so rather archaic and (sorry Josiah) stuffy in tone while also being deeply overtly deliberatively Christian in content, theme and message, which makes every poem, no matter how artful (and they are artful - the majority of the poems in this book are as technically well-constructed as their theology is orthodox-Anglican), feel somewhat like you're being sermonised at.
The poetry is all lumped together in one big collection called The Church, with poems (mostly rather short, and often sonnets, which seem to be a particular specialty of Herbert's) unsurprisingly centring thematically around classic weighty Christian concepts, such as consciousness of one's own sin, prayer, confession, hope, grace, forgiveness, love, joy, peace, etc. This bulk of the book is prologued by a longer poem called The Church Porch which is much meatier in terms of a challenging mental/spiritual engagement as it explores the inner dynamics of a person weighing themselves up before entering a church (in both a day-to-day instance and in the lifelong sense), and epilogued by another longer poem called The Church Militant which is a triumphal hearty toot on the eschatological trumpet of what God's people look like from an eternal perspective.
Alongside the poetry which forms the core backbone of the collected works, there is a 37 chapter prose piece called The Country Parson which is half essay, half sermon, half manual on how to be an effective parish priest (I will freely admit I somewhat skimmed this - it has a good deal of wisdom in it but nothing particularly groundbreaking), and a compiled list of 1,024 "Outlandish Proverbs", which initially I was rather excited by as I assumed George had come up with them all himself - however it seems more that he simply collected folksy wisdom from all over the place and put it all together in one big wodge (some of which is retained in proverb and idiom to this day, some of which is mere tautology or common-sensical to the point of banality, and some of which is downright impenetrable). Finally there is a small array of letters, lectures, translations, and his will, none of which I bothered to read at all.
Christian readers who enjoy neatly-constructed if somewhat repetitive and decidedly unadventurous poetry will find a lot of edifying stuff in this book. Non-Christian poetry enjoyers will probably find it coming on far too strong a moralising and proselytising voice to read past. And non-Christian non-poetry enjoyers probably have no reason whatsoever to engage with the works of George Herbert unless it's part of your current academic syllabus to whatever extent. All that said, receiving this book four years ago was a significant moment in helping me claw me way back to sanity, so I will forever owe it that at least.
