An act performed by a master of nature without reference to the facts in nature. This is the only honest definition of a miracle. If a man could make a perfect circle, the diameter of which was exactly one-half the circumference, that would be a miracle in geometry. If a man could make twice four, nine, that would be a miracle in mathematics. If a man could make a stone, falling in the air, pass through a space of ten feet the first second, twenty-five feet the second second, and five feet the third second, that would be a miracle in physics. If a man could put together hydrogen, oxygen and nitrogen and produce pure gold, that would be a miracle in chemistry. If a minister were to prove his creed, that would be a theological miracle. If Congress by law would make fifty cents worth of silver worth a dollar, that would be a financial miracle. To make a square triangle would be a most wonderful miracle. To cause a mirror to reflect the faces of persons who stand behind it, instead of those who stand in front, would be a miracle. To make echo answer a question would be a miracle. In other words, to do anything contrary to or without regard to the facts in nature is to perform a miracle. Now we are convinced of what is called the "uniformity of nature." We believe that all things act and are acted upon in accordance with their nature; that under like conditions the results will always be substantially the same; that like ever has and ever will produce like. We now believe that events have natural parents and that none die childless. Miracles are not simply impossible, but they are unthinkable by any man capable of thinking. Now an intelligent man cannot believe that a miracle ever was, or ever will be, performed. Ignorance is the soil in which belief in miracles grows. III. Let us take another step: While our ancestors filled the darkness with evil spirits, enemies of mankind, they also believed in the existence of good spirits. These good spirits sustained the same relation to God that the evil ones did to the Devil. These good spirits protected the faithful from the temptations and snares of the Evil One. They took care of those who carried amulets and charms, of those who repeated prayers and counted beads, of those who fasted and performed ceremonies. These good spirits would turn aside the sword and arrow from the breast of the faithful. They made poison harmless, they protected the credulous, and in a thousand ways defended and rescued the true believer. They drove doubts from the minds of the pious, sowed the seeds of credulity and faith, saved saints from the wiles of women, painted the glories of heaven for those who fasted and prayed, made it possible for the really good to dispense with the pleasures of sense and to hate the Devil. These angels watched over infants who had been baptized, over persons who had made holy vows, over priests and nuns and wandering beggars who believed.
