In Kolde's opinion, the Apology is a companion volume, as it were, to Melanchthon's _Loci Communes,_ and a theological dissertation rather than a confession. However, theological thoroughness and erudition do not conflict with the nature of a confession as long as it is not mere cold intellectual reflection and abstraction, but the warm, living, and immediate language of the believing heart. With all its thoroughness and erudition the Apology is truly edifying, especially the German version. One cannot read without being touched in his inmost heart, without sensing and feeling something of the heart-beat of the Lutheran confessors. Jacobs, who translated the Apology into English, remarks: "To one charged with the cure of souls the frequent reading of the Apology is invaluable; in many (we may say, in most) parts it is a book of practical religion." (_The Book of Concord_ 2, 41.) The Apology does not offer all manner of theories of idle minds, but living testimonies of what faith, while struggling hotly with the devil and languishing in the fear of death and the terrors of sin and the Law found and experienced in the sweet Gospel as restored by Luther. In reading the Apology, one can tell from the words employed how Melanchthon lived, moved, and fairly reveled in this blessed truth which in opposition to all heathen work-righteousness teaches terrified hearts to rely solely and alone on grace. In his _History of Lutheranism_ (2, 206) Seckendorf declares that no one can be truly called a theologian of our Church who has not diligently and repeatedly read the Apology or familiarized himself with it.
