How is Immanuel Kant's Categorical Imperative compatible with a religious perspective?

To begin with we need to break down the Categorical Imperative. Firstly, into what a Categorical Imperative is, an absolute and unconditional requirement based on reason. Then, into the three main sections which comprise it: only act when that act can reasonable become a universal law, treat humans as an end in themselves and finally, act if you are part of the universal kingdom of ends. To highlight further knowledge, it may be advisable to show an understanding of Kant's view on religion. This will provide us with an introduction and a solid basis on which to make our comparison.
After the basic idea of the Categorical Imperative has been set up, we can then begin the religious comparison (in this example I will use Christianity). To provide the best structured and clearest answer, I will go through the Categorical Imperative step by step, drawing comparison with Christianity. First we shall draw comparison with Kant's qualification of universal law. We can, therefore draw the simple comparison with the ten commandments, providing specific examples, such as thou shall not kill. For a more sophisticated comparison to expand our point, we can then go onto look at Divine Command theory and our moral obligations to God. Secondly, we shall move onto the idea of treating humans as an end in themselves. For this we can look to Jesus'teachings of agape, for example 'love thy neighbour' or 'love thy enemy', you may also recall to the ten commandments and our equality in the eyes of God. Our final comparison will be with the universal kingdom of ends. We can link this to the Christian idea of heaven, all Christians it can be argued aim for a place in heaven. To show a wider knowledge we can also link this to Kant's Summum Bonum, the highest good we all strive for. Following this, a brief conclusion showing a summary of the topics discussed. For this type of philosophy essay, the structure I would advise is, a clear introduction defining the key concept or idea being discussed. I would then break down each part of this concept into a separate paragraph, in this case three. In each paragraph the structure must show a basic point or idea, backed up with evidence, explained and then linked back to the question. To finish, a basic conclusion summarising key points concisely.
