In this study we have discussed the theology of A.A. van Ruler and considered many of the criticisms that have been levelled against it. However, we have not levelled any of our own criticisms against it. This does not mean that we are saying that Van Ruler's theology must be accepted as the perfect, irreproachable theology. Surely no one could ever write such a theology! However I do believe that there is such a lot of misunderstanding of his theology (as we can see in the above criticisms) that it is important for us to gain a correct understanding of this great theologian's ideas before we embark on a criticism of them. It is hoped that this work will contribute towards this understanding and a greater acceptance of Van Ruler's theology.
