For the instructor or student confronting an introductory course in ordinary differential equations there is a need for a brief guide to the key concepts in the subject. Important topics like stability, resonance, existence of periodic solutions, and the essential role of continuation of solutions are often engulfed in a sea of exercises in integration, linear algebra theory, computer programming and an overdose of series expansions. This book is intended as that guide. It is more conceptual than definitive and more light-hearted than pedagogic. It covers key topics and theoretical underpinnings that are necessary for the study of rich topics like nonlinear equations or stability theory. The author has included a great many illuminating examples and discussions that uncover the conceptual heart of the matter.

This commentary on the Hebrews, the General Epistles, and Revelation, excerpted from the Fortress Commentary on the Bible: The New Testament, engages readers in the work of biblical interpretation. Contributors connect historical-critical analysis with sensitivity to current theological, cultural, and interpretive issue antroductory articles describe the challenges of reading the New Testament in ancient and contemporary contexts, as well as exploring other themes ranging from the Jewish heritage of early Christianity to the contexts of diaspora. These are followed by the survey "Introduction to Hebrews, the General Epistles, and Revelation." Each chapter (Hebrews through Revelation) includes an introduction and commentary on the text through the lenses of three critical questions: The Text in Its Ancient Context; The Text in the-Interpretive Tradition; The Text in Contemporary Discussion. Hebrews, the General Epistles, and Revelation introduces fresh perspectives and draws students, as well as preachers and interested readers, into the challenging work of interpretation.

Sanchez's subject is the power of imperial myths - and the subversive power unleashed when resistance movements take over those myths for their own purposes. Moving from John of Patmos's inversion of Roman imperial mythology in Revelation 12 to the indigenous appropriation of Spanish symbolism and mythology, in seventeenth-century Mexico, Sanchez then explores the continuing power of the Virgin of Guadalupe (La Guadalupena) to inspire movements for a better society in our own day. From Patmos to the Barrio reveals new insights into the biblical Apocalypse of John, and the enduring power of its legacy down to the present day, as well as translations of two important 17th century documents concerning La Guadalupena: Luis Laso de la Vega's Huei tlamahuicoltica and Miguel Sanchez's Imagen de la Virgen Maria. Also included are images of La Guadalupena in the murals of East Los Angeles.
