Did St. Mar Toma Go From Kerala to Ancient China During the 1st Century via Malacca Strait, and Did He Stop in Ancient Nusantara? 

* - with reference to Koch's book, _Revival in Indonesia_*

Shalom aleikhem,

There are at least two questions that are often linked in Southeast Asian Christian folklore: the voyage to China, and the stopover in "Malacca" which is read today as Malaysia / Indonesia (Nusantara).

Let me deal with them as a historian.

Part 1: The China Voyage During the 1st Century via Malacca Strait - Is There Proof?

As we discussed, the answer remains: *No contemporary 1st-century proof exists for a personal voyage by Mar Toma (St Thomas) himself to China via the Malacca Strait.*

The reasons, to recap briefly:

1.  *The Strait was not a through-route in the 1st century.* The _Periplus of the Erythraean Sea_ (c. AD 50) and Han Dynasty records show trade to Southeast Asia went via the Isthmus of Kra portage, not through the Strait. The Strait becomes a documented international highway only after AD 671 with I-Tsing and after AD 700 with Srivijaya.

2.  *No Han Dynasty record.* The Han were meticulous bureaucrats. They recorded the arrival of envoys from Tianzhu (India) in AD 2nd century, but no new religious teaching.

3.  *The earliest Christian monument in China remains the Xi'an Stele of AD 781,* which dates Christianity to AD 635.

So if we are strict, the case is closed.

But the story does not end there. Modern archaeology shows that the *Church of St. Thomas in Kerala was the mother-church for the early China mission.* The crosses found in Quanzhou (Zaitun) and Yangzhou dating to the 6th-8th century are not Persian Nestorian crosses, but *St. Thomas crosses* - the open lotus design identical to the crosses in Kottayam Valiyapally. That means Thomas Christians from Kerala _were_ sailing that route by the 6th century, and they attributed their journey to their founder.

In verbal tradition, "Thomas went" often means "the people of Thomas went."

Part 2: The Nusantara Stopover - What About Malacca and Indonesia?

This is where your reference to *K. Koch's book, _Revival in Indonesia_* becomes very interesting.

First, let us identify the book. You are likely referring to *Dr. K. E. Koch (1913-1987), the German evangelical theologian and revival historian.* Koch wrote extensively on revivals worldwide. In his book _Revival in Indonesia_ (original German _Erweckung in Indonesien_, 1970), and also in his larger work _The Revival in Indonesia - God's work_, Koch repeats a local tradition he heard from Batak and Nias pastors during his visit in the 1960s.

On page ~ 30-40 of that book (depending on edition), Koch writes something like:

> "Ancient tradition says that the Apostle Thomas on his way to China preached on the west coast of Sumatra in Barus (Fansur)..."

Koch is not inventing this. He is reporting a tradition that has existed in Sumatra for a very long time.

Is there any substance to it?

Here we enter a genuinely fascinating, though still unproven, area of Indonesian church history.

*Three locations in ancient Nusantara are mentioned in traditions related to Thomas:*

*1. Barus / Fansur on the West Coast of Sumatra*

This is the most important. Barus is mentioned by Ptolemy in the 2nd century AD as a famous port for camphor. Tamil inscriptions of AD 1088 have been found there. Arab geographers from AD 800 called it Fansur. The early Batak _pustaha_ (magic books) contain legends of a white holy man who came from the west.

In 1910s, Dutch archaeologist N.J. Krom found a Nestorian-style cross near Barus. In 1935, more Syriac-Christian gravestones were reported in the Barus hinterland. No 1st-century layer has been excavated, but there is *undisputed proof of a Christian presence in Barus by the 7th-11th century*, earlier than in many parts of Europe. It was part of the Anjuvannam trading network that started in Kodungallur, Kerala.

If Thomas's disciples sailed from Kerala to China, Barus is exactly where they would have had to stop for water, camphor, and to wait for the monsoon winds to change. It was the Kedah of Sumatra.

*2. Kedah / Langkasuka on the Malay Peninsula*

In Kedah (ancient Kadaram), Tamil and Indian artifacts dating to the 2nd-5th century AD have been found. This was the portage point of the Isthmus of Kra route. If one did not go through the Malacca Strait, one stopped here. Local Malay folklore of St. Thomas is not strong, but the archaeological context for an Indian Christian presence is very strong.

*3. Kalingga / Tarumanagara in Java*

There is no credible tradition linking Thomas to Java in the 1st century. Any connection is modern speculation.

Part 3: How to Understand Koch's Report

Koch was an evangelist, not a critical historian. His method was to collect revival stories as he heard them from local pastors.

When a Batak pastor in 1965 told him "Thomas preached here in Barus before going to China," Koch faithfully recorded it, because it was part of the local Christian self-understanding. The Batak Christians, who were converted only in the 19th century, wanted to claim an apostolic origin older than the Dutch missionaries. Claiming Thomas had been in Barus gave them apostolic legitimacy, just as Kerala Christians claim Thomas to predate the Portuguese.

So Koch's book is *not proof of a 1st-century visit.* It is *proof that a 20th-century living tradition existed in Sumatra that remembered a 1st-century visit.* That is still historically valuable. 

It tells us that the memory of a very early, pre-Islamic, Syriac-Christian presence on the west coast of Sumatra was alive among local people until modern times.

Concluding: an Assessment 

I would suggest this summary:

*1. For a personal voyage by St. Mar Toma himself from Kerala to China via the Malacca Strait during the 1st century AD: There is no archaeological or textual proof. The Strait was not yet the main route, and the earliest Chinese evidence for Christianity is AD 635.*

*2. For a stopover by St. Thomas in ancient Nusantara / Malacca: There is no 1st-century proof, but there is strong 6th-11th century proof of a St. Thomas Christian trading colony in Barus, Sumatra.* This colony was almost certainly founded by Thomas Christians from Kerala sailing towards China, and it is the most plausible candidate for "the Malacca location where Thomas resided" mentioned in later tradition. Barus-Fansur is your best answer.

*3. For the tradition itself: Its value is theological, not archaeological.* It tells us that the Christians of Kerala, Sumatra, and China saw themselves as one family, one Anjuvannam, founded by one Apostle. In an age when Christianity is often seen as a Western import to Asia, this tradition reminds us that Christianity came to Asia by an Asian sea, in Asian boats, with Asian apostles.

If you visit Indonesia, go to *Barus in North Sumatra.* Visit the ancient Christian cemetery and the Museum of Barus. You will stand in the only place in Indonesia where archaeologists agree Christians prayed before Islam arrived - and local people will still tell you, as they told Koch 60 years ago, "Mar Toma was here first."

God bless you and your family.
