Only Son, Our Lord

Written in 1973, 'Knowing God' by J.I. Packer is a seminal work that divides into three main sections. The first section, 'Knowing the Lord,' focuses on how and why we know God, emphasizing the importance of listening to God’s word and understanding His nature. The second section, 'Behold Your God,' delves into the attributes of God such as His love, grace, wisdom, justice, and sovereignty. The third section explores the practical applications of knowing God, including the gospel message and what it means to live as a Christian. Packer stresses that knowing God is not merely intellectual but involves a heartfelt and voluntary application of truths about God to daily life, leading to a deeper fellowship with Him and a life of worship and obedience.

The Heidelberg Catechism is a significant theological document of the Protestant Reformation. Written in 1563 in Heidelberg, Germany, it serves as a confession of faith for many Reformed churches. Composed of 129 questions and answers, it systematically covers key doctrines of Christianity, including sin, redemption, and gratitude. Its warm, pastoral tone and emphasis on personal comfort in Christ have made it a beloved resource for believers seeking a deeper understanding of their faith.

The Westminster Confession of Faith is a systematic exposition of Calvinist theology, influenced by Puritan and covenant theology. It includes doctrines common to most of Christianity, such as the Trinity and Jesus' sacrificial death and resurrection, as well as specific Protestant doctrines like *sola scriptura* and *sola fide*. The confession was drawn up between 1643 and 1649 by the Westminster Assembly, which was called by the English Parliament to reform the Church of England. It consists of 33 chapters and 186 paragraphs, covering topics such as Scripture, God, man and sin, Christ and salvation, and the Christian life. The document has been influential in defining the belief and practice of Presbyterian churches and has been adopted by various other Christian denominations.

Robert Letham's The Eternal Son offers a sustained theological and historical treatment of the person of the Son within the Trinity, arguing that Christology is central to the Christian faith. The book traces ecumenical debates—especially the often-neglected councils after Chalcedon—showing how questions about the Son's person affect soteriology and doctrine. Letham defends the orthodox position that the eternal Son assumes a true human nature without change to his divine person and critically engages modern biblicist and revisionist proposals. He includes pastoral implications, discussion of adoption and atonement, and appendices addressing contemporary confusions. The work is written for pastors, scholars, and students concerned with reclaiming historic Trinitarian and Christological clarity.
