Discipleship is a foundational concept of Christian life which has become a popular and ubiquitous description of belonging and growth in early 21st century ecclesiastical language. Discipleship courses and popular writings abound, and the term is used liberally in official church documents and strategies for growth and development, particular in a western context. But does recent use of the word risk reducing the wide range of meanings of discipleship to something less rich and inclusive than is warranted? With contributions from an array of leading thinkers, scholars and theologians, including Rachel Mann, Kirsteen Kim and Anthony Reddie, this book argues that there is need for more clarity, precision and depth in defining what meaningfully and constructively is construed as discipleship. Beginning with an overview of how the concept of discipleship has been understood in history, the volume goes on to consider some of the key figures who have shaped our understanding of the concept, and finally to reflect on what discipleship might look like in contemporary society.

This is a guide to the archaeology of the British Isles, from the Ice Age to the medieval period. Beginning with an introduction to the methods and techniques of modern archaeology, the author moves on to cover the archaeology of the British Isles, dealing with such questions as: when the British Isles were first inhabited; how the great Neolithic monuments were planned and built; and the impact of the Roman Conquest. The guide is completed by a detailed gazetteer of 468 sites that can be visited.

The Go Workshop will take the pain out of learning the Go programming language (also known as Golang). It is designed to teach you to be productive in building real-world software. Presented in an engaging, hands-on way, this book focuses on the features of Go that are used by professionals in their everyday work. Each concept is broken down, clearly explained, and followed up with activities to test your knowledge and build your practical skills. Your first steps will involve mastering Go syntax, working with variables and operators, and using core and complex types to hold data. Moving ahead, you will build your understanding of programming logic and implement Go algorithms to construct useful functions. As you progress, you'll discover how to handle errors, debug code to troubleshoot your applications, and implement polymorphism using interfaces. The later chapters will then teach you how to manage files, connect to a database, work with HTTP servers and REST APIs, and make use of concurrent programming. Throughout this Workshop, you'll work on a series of mini projects, including a shopping cart, a loan calculator, a working hours tracker, a web page counter, a code checker, and a user authentication system. By the end of this book, you'll have the knowledge and confidence to tackle your own ambitious projects with Go.Key Features Build a comprehensive foundation in Go and focus on developing real-world applications Explore the Go Standard Library and learn how to structure your code Learn how to efficiently interact with files, databases and REST APIs What you will learnUnderstand Go syntax and use it to handle data and write functions Debug your Go code to troubleshoot development problems Safely handle errors and recover from panics Implement polymorphism by using interfaces Work with files and connect to external databases Create a HTTP client and server and work with a RESTful web API Use concurrency to design software that can multitask Use Go Tools to simplify development and improve your code Who this book is forThe Go Workshop is designed for anyone who is new to Go.

No prior programming experience is necessary.

In a period where Christianity was only beginning to form a definitive identity, Marcion played a remarkable and generative role. Andrew Hayes takes the measure of his impact on second-century Christianity through a close examination of the topics and structure of Justin Martyr's writings, especially the Dialogue with Trypho, demonstrating that Justin repeatedly described Christianity in a contra-Marcionite fashion. Arguing that the early part of the Dialogue is in fact a contra-Marcionite prelude to all the major themes in the rest of the piece, Hayes claims that the chief task Justin took for himself was to seize back from Marcion the terms of Christian self-definition. Marcion is thus far more important for Justin's work than the few places where he is explicitly named might suggest, and Hayes shows that these texts are far from anomalous: they reveal Justin's deeper agenda of presenting Marcion as a demonic instrument. Students of the second century, of Marcion and of Justin alike, will find much to reevaluate in these pages.

A detailed study of a cycle of fourth-century liturgical poems, in Syriac, dedicated to a great pioneer of the Syriac ascetical tradition. Hayes analyzes its various portraits of the saint, shaded differently by Ephrem and his later imitators.
