The two most common databases for full-text articles in theology are ATLA Religion and ProQuest Religion. JSTOR is also a useful database for general articles in theology and religion that focuses on older/ classic periodic literature.
These are found on the Hubbard Library's database page, under theology in the "subjects" drop down menu. You can also use the search bar to quickly find a specific database title.
Reference articles can be located through the Credo Reference database, and many relevant scholarly monograph chapters can be located on the Oxford Scholarship Online (Religion) database.
The first two of these databases are also searchable through the library catalog under default search settings. You can add additional theology databases to your catalog search using advanced search. After clicking "Advanced Search," click the "Select All in Group" button under the "Theology" category. Then click "Save Changes."
After searching for your desired subject, you can use the search tools on the left column to limit your search results to Fuller Libraries and articles only. See the screen shot below:
