"Buom yn disgwyl yn hir am y gyfrol hon... Yr oedd y cawr hwn bedair canrif o flaen ei amser, ac fe ddiystyrwyd disgleirdeb ei weledigaethau gan genedllaethau. Diolch i'r Dr John Morgans am roi cyfle inni, mewn cyfrol gynhwysfawr, gael gweld drosom ein hunain fawredd y Cymro rhyfeddol hwn o Gaerdydd."
- John Gwilym Jones
"John Morgans deserves our thanks for seeking to rescue him from the neglect of posterity. Readers of this book will surely be glad of the opportunity to sample some of the delights of Erbery's colourful writings."
- Geraint H. Jenkins, Morgannwg - The Journal of Glamorgan History
"Bydd y sawl a ddarlleno'r llyfr hwn yn cael mewnwelediad eglur i brif ddadleuon y cyfnod, pan fu cymdeithas ac ymarferion crefyddol yn cael eu hailddyfeisio. Mae'n bosibl fod agen y fath ailddyfeisio heddiw. O ganlyniad, efallai ei fod yn addas i adael i Erbery lefaru unwaith eto."

"If you want a glimpse of the exhilarating chaos of mid-17th century religion, you will find it here.
- Dr Alec Ryrie, Church Times
"Those who read this book will gain insights into the major debates of a period when society and religious practice were being reinvented. Such reinvention may well be needed today. It is, then, perhaps appropriate that Erbery speaks again.
