An excellent example of this is the doctrine of the Trinity. It is a logical consequence. It derives a conclusion from a given fact or premise. It is the deduction of one proposition from another proposition. Such inferential facts or propositions are sufficiently binding when their truth is established by competent and satisfactory evidence.
Competent evidence means such evidence as the nature of the thing to be proved admits.
Satisfactory evidence means that amount of proof which would ordinarily satisfy an unprejudiced mind beyond a reasonable doubt. Jesus used this rule when he proved the resurrection of the dead to the unbelieving Sadducees in Matt. Learning these eight rules and properly applying them will help keep any interpreter from making errors and will hopefully alleviate many of the disagreements unfortunately present in Christianity today. I urge you, if you have not already done so, to examine the claims and the work of Jesus Christ and to receive Him as your Saviour.
