"One of the Holy Trinity Suffered for us." This formula, proposed by the Scythian monks, became the test of orthodox Christology in the sixth century and stands as a testimony that in Christ there is no barrier between his divinity and our humanity. This formula is a truly fitting title for this festschrift honoring the faithful service of Dr. William Weinrich. This book is composed of theological essays that celebrate three areas where William Weinrich has made significant contributions. The first part is entitled Evangelion and consists in essays honoring Weinrich's exegetical work with Johannine texts. The second part, Theologia, is composed of essays honoring Weinrich's theological work in Patristics and the History of the early church. The final part, Ecclesia, consists in practical essays that recognize Weinrich's selfless service training pastors and leading the church.
