Life of Soul (Lyfe of Soule) is a short anonymous prose tract written in the late Middle English of the English midlands about 1400 or a little earlier.
The tract takes the form of a catechetical dialogue, or at least begins that way, one interlocutor falling silent about halfway through; of the three surviving versions, version L represents itself as a conversation between two "friends in Christ"; versions A and H replace this pair with a questioning sister and answering brother and a questioning son and answering father respectively. Life of Soul consists of six questions together with the corresponding answers. The first five questions are introductory, the sixth provokes a lengthy reply that forms the bulk of the tract. The tract begins with the eternal question, "How does one get to heaven?"; answers, "Through Christ who is the life of our soul" --identifying that life with faith and renunciation of sin--; and proceeds to the final question that forms the structural motif for the tract: "What are the food and drink that nourish the life of soul?" The rest of the text explicates the answer: the soul's bread is faith in Christ and its drink is adherence to his words. Faith in Christ is divided into faith in his divinity and faith in his humanity, the relevant tenets of the creed being listed under each. Christ's words are explained as being summed up in the two commands of love: to love God and one's brother. These two words, it is explained, comprise all ten of the Mosaic ten commandments (duly listed and accounted for); they combat the seven deadly sins (each duly listed, its defeat by love explained); they inspire their adherents to perform the corporal works of mercy(duly listed); and they nourish and are nourished by six virtues: peaceableness, patience, meekness, poverty in spirit, truth, and chastity. Each virtue is then exemplified, largely from the Sermon on the Mount; meekness by, among other things, the Lord's Prayer as the exemplarly prayer of the meek, a device which allows the author to expound the Lord's Prayer.
Version L of Life of Soul (the version that forms the basis for available modern editions) appears to have been addressed to a lay audience, version A perhaps adapted for "religious" (i.e., those who, like monks, live under a rule). Two features of the tract would suit it for a monastic audience: the constant use of the words "brother" and "brethren" to describe fellow Christians; and the subject matter of the work: Christian perfection, especially as that is laid out in the so-called "Evangelical counsels" or "counsels of perfection" found in Christ's Sermon on the Mount (Matthew 5-6). According to a considerable tradition, these "counsels," too demanding to be imposed on the ordinary believer, are the preserve of those with a calling to the monastic life. But the counsels to perfection were embraced by many individuals and movements that were not monastic; and there is nothing specifically monastic about their interpretation here: the work inculcates faith, good works, and the avoidance of such universal faults as anger, pride, and malicious gossip. Even poverty and chastity are recommended in universal terms. The tract also mentions Christ's strictures against divorce, hardly relevant to monks. It is noteworthy that version A, perhaps adapted for a monastic audience, adds to this section the comment, "In order to set us an example of chastity, Christ chose for his lifespan this manner of life [i.e., celibacy], as did many of his apostles." The social class of the audience is similarly difficult to specify. The author addresses remarks to both the poor, who are warned that material poverty in itself is valueless, and the rich, who are warned that wealth used selfishly damns the possessor. These warnings could well be directed toward contemporary society (e.g., toward friars and prelates respectively), rather than toward actual members of the anticipated readership.
