The church was in Golden Square, of which it may be said that it is neither a square nor yet golden, but a dingy close or court opening by an archway from the High Street, the main thoroughfare of Berwick. The building was till recently a tannery, but the main features of it are still quite distinguishable. It stood on the left as one entered from High Street, and it had the usual high pulpit at its farther end, with a precentor's desk beneath it, and the usual deep gallery supported on metal pillars running round three of its four sides. The manse, its door adorned with a decent brass knocker, stood next to the church, on the side farthest from the street. It gave one a pleasant surprise on entering it to find that only its back windows looked out on the dim little "square." In front it commanded a fine view of the river, here crossed by a quaint old bridge of fifteen arches, which, owing to the exigencies of the current, is much higher at the Berwick end than at the other, and, as an Irishman once remarked, "has its middle all on one side." For some little time, however, after Cairns's settlement, he did not occupy the manse, but lived in rooms over a shop in Bridge Street; and when at length he did remove into it, he took his landlady with him and still remained her lodger.
For the first five years of his ministry Cairns devoted himself entirely to the work which it entailed upon him, and steadily refused to be drawn aside to the literary and philosophical tasks which many of his friends urged him to undertake. He had decided that his work in Berwick demanded his first attention, and, until he could ascertain how much of his time it would absorb, he felt that he could not go beyond it. On the early days of the week he read widely and hard on the lines of his Sunday work, and the last three days he devoted to writing out and committing to memory his two sermons, each of which occupied about fifty minutes in delivery. The "committing" of his sermons gave him little or no trouble, and he soon found that it could be relegated without anxiety to Saturday evening. And he got into the habit of preparing for it by a Saturday afternoon walk to the little yellow red-capped lighthouse at the end of Berwick Pier. At the upper end of the pier was a five-barred gate, and on the way back, when he thought that nobody was looking, he would vault over it with a running leap.
His preaching from the first made a deep impression. Following the old Seceder tradition, and the example of his boyhood's minister Mr. Inglis, and of his professor Dr. Brown, his discourse in the forenoon was always a "lecture" expository of some extended passage of Scripture, and forming one of a consecutive series; while that in the afternoon followed the familiar lines of an ordinary sermon. But there was nothing quite ordinary in his preaching at any time. Even when there was no unusual flight of eloquence, there was always to be noted the steady march of a strong mind from point to point till the conclusion had been reached; always a certain width and elevation of view, and always the ring of irresistible conviction. And although the discourse had been committed to memory and was reproduced in the very words that had been written down in the study, no barrier was thereby interposed between the preacher and his hearers. Somehow—at least after the first few paragraphs—when he had properly warmed to his work, the man himself seemed to break through all restraints and come into direct and living contact with his hearers.
His action sermon, i.e. the sermon preached before the Communion, was always specially memorable and impressive. He had the subject chosen weeks, and sometimes even months, beforehand, and, as he had no other sermon to write for the Communion Sunday, he devoted the whole of the preceding week to its preparation. His action sermons, which were those he usually preached on special occasions when he was away from home, dealt always with some theme connected with the Person or Work of Christ. They were frequently apologetic in their conception and structure, full of massive argument, which he had a remarkable power of marshalling and presenting so as to be understood by all; but the argument, reinforced by bursts of real eloquence, always converged on the, exaltation of the Redeemer. "I never thought so much of him as I do to-day," said one of his hearers to another after one of these sermons, "I never thought so much of Christ as I do to-day," replied the other; and that reply showed that in at least one case the purpose of the preacher in preparing and delivering his sermon had been fulfilled.
On the Sunday evening Cairns had a Bible-class of over one hundred young men and women, to which he devoted great care and attention. "It was the best hour of the day to us," wrote one who was a member of this class. "He was nearer us, and we were nearer him, than in church. The grandeur and momentum of his pulpit eloquence were not there, but we had instead a calm, rich, conversational instruction, a quiet disclosure of vast stores of information, as well as a definite dealing with young hearts and consciences, which left an unfading impression."
But Cairns was no mere preacher and teacher. He put out his full strength as truly in his pastoral work as in his work for and in the pulpit. He visited his large congregation statedly once a year, offering prayer in each house, and hearing the children repeat a psalm or portion of Scripture which he had prescribed the year before. He timed these visits so accurately that he could on one occasion banter one of his elders on the fact that he had received more than his due in one year, because the last visitation had been on the 1st of January and this one was on the 31st of December. A good part of his visiting had to be done in the country, because a considerable section of his congregation consisted of farmers or hinds from Northumberland, from the "Liberties of Berwick," and even from Scotland, which first begins three miles out from the town. These country visitations usually concluded with a service in a barn or farm-kitchen, to which worshippers came from far and near.
But besides this stated and formal visitation, which was intimated from the pulpit, constant attention was bestowed on the sick, the bereaved, the poor, the tempted, and all others who appealed specially to the minister's heart or his conscience. And yet there was no sense of task-work or of a burden to be borne about his relations to his congregation. His exuberant frankness of manner, contrasting as this did with the reserved and somewhat stiff bearing of his predecessor Dr. Balmer, won the hearts of all. And his keen sense of the ludicrous side of things often acted as an antiseptic, and kept him right both with himself and with his people.
Once, however, as he used to tell, it brought him perilously near to disaster. He was in the middle of his sermon one Sunday afternoon in Golden Square. It was a hot summer day, and all the doors and windows were open. From the pulpit he could look right out into the square, and as he looked he became aware of a hen surrounded by her young family pecking vigorously on the pavement in search of food, and clucking as she pecked. All at once an overwhelming sense of the difference between the two worlds in which he and that hen were living took possession of him, and it was with the utmost difficulty that he restrained himself from bursting into a shout of laughter. As it was, he recovered himself with a mighty gulp and finished the service decorously enough.
Cairns was also assisted in his work by his phenomenal powers of memory. After reading a long sermon once, or at most twice over, he could repeat it verbatim. Once when he was challenged by a friend to do so, he repeated, without stopping, the names of all the children in his congregation, apologising only for his imperfect acquaintance with two families who had recently come. Another instance of this is perhaps not so remarkable in itself, but it is worth mentioning on other grounds. Five-and-thirty years after the time with which we are now dealing, when he was a professor in Edinburgh, some of his students were carrying on mission work in a growing district of the city. An iron church was erected for them, but the contractor, an Englishman, before his work was finished was seized with illness and died. He was buried in one of the Edinburgh cemeteries, and Dr. Cairns attended the funeral. Having ascertained from the widow of the dead man that he had belonged to the Church of England, he repeated at the grave-side the whole of the Anglican Burial Service. When he was asked afterwards how he had thus come to know that Service without book, he replied that he had unconsciously got it by heart in the early days of his Berwick ministry, before there was either a cemetery or a Burials Act, when he had been compelled to stand silent and hear it read at the funerals of members of his own congregation in the parish churchyard.
Rather more than a year and a half after his ordination, in May 1847, the Secession Church in which he had been brought up, and of which he was now a minister, entered into a union with another of the Scottish non-Established Churches, the Synod of Relief. There was thus formed the United Presbyterian Church, with which his name was afterwards to be so closely associated. The United Church comprised five hundred and eighteen congregations, of which about fifty were, like those in Berwick, in England; the nucleus of that English Synod which, thirty years later, combined with the English Presbyterian Church to form the present Presbyterian Church of England. References in his correspondence show that this union of 1847, which afterwards had such happy results, excited at the time little enthusiasm, and was entered into largely as a matter of duty. "It is," he writes, "like the union, not of two globules of quicksilver which run together of themselves, but of two snowballs or cakes of mud that need in some way very tough outward pressure. I hope that the friction will elicit heat, since this neither cold nor hot spirit is not to edification."
