Theology is the fruit of the reflection of the truth revealed in the Word of God.” (Louis Berkhof, 1996)
Theologians have found several sources from which they develop the ideas of God. The firs source is Reason, it is defined narrowly as the logical deduction from stated premises, or broadly to include ones feelings, intuition, and experience. This point out that one can find his way to God through his own thought, reasoning, contemplation etc. the best example of such a source is though St. Anselm, who developed the ontological argument for the existence of God. Church authority can also be a source of Christian theology, to give a an example the roman Catholic Church gives teaches that God reveals his truth to the church in some collective way, the church also claims that god can manifest himself directly through the leaders of the church. The third source can be through General Revelation, it is said by many that God’s person and character is revealed in nature. When man contemplates about nature it is with no doubt that he is having a true knowledge of God. Evidentialist apologists of England can epitomize this source.
The fourth source through which source of theology can manifest itself is by Special revelation, the Bible claims to be a direct revelation to man from God. The belief of Christianity is that the Bible should help them to acquire and organize the teachings found there. The other source of Christian theology can be from the postmodern theology’s sources of theology. Therefore the sources of theology to summarize are through God himself. God should be the only source of knowledge in regard to his own being and relations. This makes theology to be a summary and explanations of the content of God’s revelations. These are; the revelation of God in nature, supremely and the revelation of God in the scriptures.
Earlier we have defined theology as “the study of god” the term Systematic is taken from the Greek word
