Beausobre and Lenfant said the following about this matter:

          The Holy Ghost, with whose help and teaching the evangelists and the apostles wrote, did not prescribe any particular language for them, but conveyed the meanings to their hearts through intuition and protected them from being involved in errors. They were allowed to preach or write the word of inspiration in their own language using their own expressions. As we find differences of expression and idiom in the writings of the ancient writers, which are mainly dependent on the temperaments and capabilities of the writers concerned, so an expert of the original language will easily recognise the differences of idiom and expression in the gospels of Matthew, Luke, and John and the epistles of Paul.

          If, however, the Holy Ghost had truly inspired the words to them, this would have not happened. The style and expression of all the gospels would have been identical. Besides, there have been many events the description of which does not require inspiration. For example, they write of many events which they saw with their own eyes or heard from reliable observers. Luke says that when he intended to write his gospel he wrote the descriptions according to eye witnesses of the events described. Having this knowledge in his mind, he thought that it was a treasure which should be conveyed to future generations.

          An author who received his account through the inspiration of the Holy Ghost usually expressed this fact by saying something to the effect that everything he had written was according to inspiration he had received from the Holy Ghost. Though the faith of Paul is of an unusual kind, it is still strange that Luke does not seem to have any witnesses except Paul and his companions.

          We have produced above the testimony of two of the great scholars of Christianity, who are very much esteemed and celebrated in the Christian world. Home and Watson have also the same opinion of them.
