There are times when careful investigation is rightly called for. When doubting Thomas demanded to see the print of the nails, and touch and handle the flesh of the risen Christ, before he would believe in the resurrection of his Lord, his demand for the most solid proof of the great marvel was a wise and commendable one; one for which all subsequent generations of Christians are deeply indebted to him. To believe without evidence, or to suppress doubt where it legitimately arises, is both fostering superstition and exposing ourselves to error and danger. What shall we say of the merchant who refuses to entertain any question about the seaworthiness of his vessel, but sends her off across the Atlantic undocked and unexamined, piously trusting her to the Lord? Shall we commend him? or not rather charge him with culpable negligence? And what we say of such a merchant seems to me just what we should say of the Christian who refuses to investigate the seaworthiness of that ship of faith which his ancestors have left him. In astronomy, in politics, in law, we demand what business the dead hand of the past has on our lip, our brain, our purse? Why should the dead hand of an Augustine or Calvin be exempt from giving its authority? Why should these mediaeval glimpses of truth be given the right to close our eyes to-day from seeing what we ourselves can see and speaking forth what we can hear of heavenly truth? In all other departments of knowledge, investigation has brought us up to a higher outlook, where we see the true relations of things better than before. In all other branches, God has given us new light, so that we discern things more as they really are. Science has risen by making a ladder of its earlier errors and by treading them under foot, reaching to higher truths. The Bible itself is the growth of ages; and Christian doctrine and Christian creeds have been the evolution of a still longer period. The dogmas of the churches are most manifold and conflicting. Is it not rather immodest and absurd for each church to claim infallibility for its present creed, and that wisdom died when the book of Revelation closed the Bible, or the Council of Trent or the Westminster Assembly adjourned its sitting? It seems to me that the churches ought, instead, to be willing and anxious to receive whatever new light God may grant them to-day, and with the potent clarifying processes of reason, separate the pure gold of religion from the dross and alloys of olden superstition and misguided judgment.
