I look forward to the second edition
I’m not going to address all your points, because I don’t have time and don’t know Robin’s reasoning on things like the order of content/chapters (you seem remarkably critical about that, even in the introduction).
I’m surprised by your “never questioned the traditional teaching of the Church” comment, as I thought that it’s very Reformed to be examining and testing the traditional teaching?
2 Timothy 4:3-4 is a warning that we **all **must remember e.g. Human nature is mistrusting, fearful of the unknown and desiring of revenge, therefore we have a bias to reading the Bible and seeing God that way.
In regards to “terms of right and wrong”: “Universalism, I suggest, occupies a middle ground between dogma and heresy. It is neither a teaching that all orthodox believers are expected to adhere to (in the way that the Trinity, or the union of deity and humanity in the one person of Christ are), nor one that they must avoid at all costs. Perhaps the most appropriate category to employ is that of theologoumena. … There are plenty of matters that are theologumena about which a believer may hold strong convictions. For instance, if universalism is theologumena then so is its denial, yet it is rarely suggested that a firm conviction that some people will be lost forever is in some way unorthodox (though one may argue that it is theologically inappropriate)” (Robin Parry in the introduction of ‘All Shall Be Well’)
