If you don't mind edited works, Provocations: Spiritual Writings of Kierkegaard is an excellent option. Yes, it is edited and abbreviated to make Kierkegaard more accessible, but each brief section introduces you to a different (often major) idea/component of Kierkegaard's thought. Having read about three quarters of the work prior to starting The Sickness Unto Death was no small help for me in gaining something of a grounding in Kierkegaard's philosophy/theology before tackling his (more challenging) writing directly. Furthermore, the sources from which each section of the work is taken are listed at the back, so if one was interested in learning more on a specific section, one could find the original text from which the excerpt was taken/edited and read the unedited passage for themselves. The included annotated bibliography could plausibly assist one even in finding the exact editions/paginations the editor used.
For your purposes, I'd especially recommend Part V: Christian Collisions of Provocations, as it includes writings the clergy, Biblical translation/commentary, and several of Kierkegaard's critiques of the church of his time.
