How to Reference in Turabian
Referencing an Author Cited in a Secondary Text
You may want to insert a quote or summarise the view of a particular scholar found in a text not written by that particular person.
For example, you might come across Frank Macchia quoted in David Perry's book, Spirit Baptism: The Pentecostal Experience in Theological Focus, and may want to keep Macchia's quote, which reads, "The Spirit liberates creation from within history toward new possibilities for free, eschatological existence."
It is recommended that you try to locate the original source, but if it is unavailable, both the original and secondary source must be listed. Distinguish the secondary text (the resource you are using) from the original source (that is being quoted) with the phrase "quoted in".
i. First citation in the footnotes
This refers to the first time either the secondary or the original source is referenced.
Frank D. Macchia, Baptized in the Spirit: A Global Pentecostal Theology (Grand Rapids, MI: Zondervan, 2006), 97, quoted in David Perry, Spirit Baptism: The Pentecostal Experience in Theological Focus (Leiden: Brill, 2017), 154.
ii. Subsequent citations in the footnotes are shortened
Frank D. Macchia, Baptized in the Spirit: A Global Pentecostal Theology (Grand Rapids, MI: Zondervan, 2006), 97, quoted in Perry, Spirit Baptism, 154.
Macchia, Baptized in the Spirit, 97, quoted in David Perry, Spirit Baptism: The Pentecostal Experience in Theological Focus (Leiden: Brill, 2017), 154.
Macchia, Baptized in the Spirit, 97, quoted in Perry, Spirit Baptism, 154.
iii. In the bibliography
Perry, David. Spirit Baptism: The Pentecostal Experience in Theological Focus. Leiden: Brill, 2017.
The bibliography should only contain the resource that you referred to. Only include the original source information in the bibliography if you actually found and read the source itself - in which case, you will reference both separately as per normal.
