{{See also|Helvetic Confessions|}}

Bullinger was part of the drafting of the ''First Helvetic Confession'', an early consensus document of the Reformation and expression of Swiss theology.<ref name="EB1911" />

Bullinger was also part of the drafting of the ''Second Helvetic Confession'' of 1566, which he originally drafted himself in 1562 as a personal statement of faith.<ref name="EB1911" />

==== ''The Decades'' ====
Bullinger's main theological work was the ''Dekaden'', or ''The Decades'', which is a compilation of 50 sermons that Bullinger published from 1549 to 1551.<ref name=":6">{{Cite magazine |last=Campi |first=Emidio |date=2004 |title=Bullinger the Theologian |url=https://www.der-nachfolger.ch/content/e850/e793/Annex_01_16_Engl._2004.pdf |magazine=Annex |location=Zürich |publisher=Beilage zur Reformierten Presse |pages=3–6 |issn=1420-9934}}</ref> Many regard ''The Decades'' to be comparable to Calvin's ''[[Institutes of the Christian Religion]]'' and [[Peter Martyr Vermigli]]'s ''Loci communes'' as an early Reformed theological explication.<ref name=":6" /> Though in sermon form, it was likely never actually delivered by Bullinger, but only written in imitation of the sermonic form. They are structured upon the [[Ten Commandments]], the [[Apostles' Creed]], the [[Lord's Prayer]], and the two Protestant sacraments. The work was quickly translated from Latin into German, French, Dutch, and English, and was one of the most popular Protestant theological works in the sixteenth and seventeenth centuries. Indeed, it was so essential that it was termed "house book" by German and Dutch translators. The Dutch, at points, even required a copy of the book to be in all Dutch trading vessels by law, which led to its spread into America and Asia.<ref name=":42">{{Cite book |last=Opitz |first=Peter |title=Architect of Reformation: An Introduction to Heinrich Bullinger, 1504-1575 |publisher=Baker Academic |year=2004 |isbn=9780801028991 |editor-last=Gordon |editor-first=Bruce |series=Texts and Studies in Reformation and Post-Reformation Thought |location=Grand Rapids |pages=101–116 |chapter=Bullinger's ''Decades'': Instruction in Faith and Conduct |editor-last2=Campi |editor-first2=Emidio}}</ref>

==== Other Theological Works ====
In 1531, Bullinger helped edit and write the preface to the ''[[Zürich Bible]]'' with Jud, Bibliander, and Pellikan.
Many of his sermons were translated into [[English language|English]] (reprinted, 4 vols., 1849). His works, mainly expository and polemical, have not been collected.

Besides theological works, Bullinger also wrote some historical works of value. The "Tiguriner Chronik" is a history of Zürich from Roman times to the Reformation; others are a history of the Reformation and a history of the Swiss confederation. Bullinger also wrote in detail on [[History of ancient Israel and Judah|Biblical chronology]], working within the framework that was universal in the Christian theological tradition until the second half of the 17th century, namely that the Bible affords a faithful and normative reference for all ancient history.<ref>Refer to [[Jean-Marc Berthoud]]'s paper for a fuller discussion.
