Perspicuity [does] not mean that every verse of the Bible is equally clear or that the meaning of any text just falls off the page into the lap of the reader. Perspicuity…refers to the overall message of Scripture, not to any individual verse. The basic meaning of salvation in Christ was clear to all who had eyes to see or ears to hear, but the details and the finer points might only be available to those who have the necessary learning and skills to divide the Word of God.
The answer is simple: for myself, I do not believe that it is appropriate that I spend my time defending my name. My name is nothing – who really cares about it? And I am not called to waste precious hours and energy in fighting off every person with a laptop who wants to have a pop at me. As a Christian, I am not meant to engage in self-justification any more than self-promotion; I am called rather to defend the name of Christ; and, to be honest, I have yet to see a criticism of me, true or untrue, to which I could justifiably respond on the grounds that it was Christ’s honour, and not simply my ego, which was being damaged. I am called to spend my time in being a husband, a father, a minister in my denomination, a member of my church, a good friend to those around me, and a conscientious employee. These things, these people, these locations and contexts, are to shape my priorities and my allocation of time. Hitting back in anger at those who, justly or unjustly, do not like me and for some reason think the world needs to know what they think of me is no part of my God-given vocation. God will look after my reputation if needs be; He has given me other work to do.
While Scripture uses public language and possesses a meaning that is accessible on one level by application of linguistic and grammatical tools, the deeper existential appropriation of that meaning by the individual, in a way that involves trust in God and true belief in the personal reality and significance of doctrines that are nonsensical to the limited human mind, such as the Trinity or the Incarnation, is only available to the mind enlightened by the Holy Spirit.
