S. P. Tregelles was one of the most noted 19th century Greek scholars. His observations back then still holds true today. He keenly writes,
[I]t has been painful to hear earnest and real desire definitely to study the Word of God regarded and termed by some, as being “occupied with the letter of Scripture.” But do those who say this know what they mean? They speak of principles, and of having their minds occupied with Christ; but how do we obtain true principles except from God’s revelation in the Word? and how does the Spirit lead the mind to be occupied with Christ, except from the definite truth of Holy Scripture? In fact, those who thus speak, putting the spirit in contrast to the letter, appear not to know what they are discussing; and as to Scripture itself, by paying but little heed to what they call “the letter,” they really disregard so far what the Spirit has there set forth. “But oh! (they say) this head-knowledge, this intellectual study of truth! how it lead our minds away from Christ!” It is true that there may be mental intelligence with but little spirituality; but it is equally true that if we obey God we shall never neglect the words of His Scripture.
Of course, with this tone of feeling, all critical study of Scripture is decried; it is deemed a waste of time. Even the study of the Word of God in the original Hebrew and Greek is spoken of as if it were a secular occupation. The English Bible is thought to be enough for teachers and taught alike; and thus they remain alike uninstructed. And if the original languages are looked at, exact scholarship is deemed superfluous. How different is this from the real study of God’s Word; from using and valuing each portion, however minute, as being from Him, and as being that of which He can unfold to us the meaning by the teaching of His Spirit…. All diligent and careful inquiry, and laborious examination of authorities, so as to know what were the very words in which the inspired writers gave forth the Scripture, is regarded as merely intellectual and secular. But is this a healthy tone of thought? Should not those who believe in the Divine authority of Holy Scripture know that they ought not to neglect its critical study? And if it be truly inspired, ought they not to feel that it is of some importance to inquire what is its true text—what, as far as existing evidence can show, were the very words in which the Holy Ghost gave it forth?
Most difficult is it to arouse Christians in general to a sense of the full importance of critical study of Scripture; and especially is this the case when dreamy apprehensions are cherished, and where vague idealism has taken the place of truth, and sentimental asceticism is the substitute for Christian holiness.
There may be an external knowledge of Scripture where there is no spiritual life or light; but that is no reason for cherishing what is supposed to be spiritual in contrast to the words of inspiration. Such a contrast cannot really exist. He who truly loves the Lord Jesus Christ, and is guided by His Spirit, will be the most subject to that which is written in the Word. True acquaintance with Scripture is the best check to mere sentimental emotion. —The Hope of Christ’s Second Coming, 1864, pp. 80-2
