(Book of Acts 6:1–6; 8:14–17; 13: 1–3). This was the system used until the arrival of Portuguese. By 1500, Malankara Church had Parish elders and a Church leader. Before the arrival of Portuguese, Latin was unknown to Malankara people. In the ‘'Decrees of The Synod of Udayamperoor'’ presented to the St. Thomas Christians in their mother tongue Malayalam, Malankara Mooppen was the name used to refer the Church leader, except on three occasions. During the period of Colonialism, (i.e., from the 16th century), the Portuguese Jesuits began deliberate attempts to annex the community into the Latin Rite of the Catholic Church, and in 1599 AD, they succeeded in their attempt through the infamous Synod of Diamper. Resentment against these forceful measures led the majority of the community under their Arkadyaqon Thomas to swear an oath never to submit to the Portuguese, known as the Coonan Cross Oath in 1653. For the first time in 1653, the Church leader was given the title Mar Thoma when Thomas Arkadyaqon was consecrated as Mar Thoma I. The present head of the Mar Thoma Church is the twenty-first Mar Thoma.

These Christians were the early evangelists of Malankara Church.

They were engaged in trade and settled down in Kodungallur. Another immigration from Persia occurred around 825 under the leadership of Persian merchant Marwan Sabriso, with two Bishops, Sapro and Prodh. Together they were known as Knanaya/Kanai people. They continued to remain partially in an endogamous group within the Nasrani community. They cooperated with the Malankara Church, attended worship services together but remained a separate identity. By the 10th century, in Malabar there were two Nazrani groups, the Saint Thomas Christians and Knanaya community. Bishops from Persia Following the arrival of Christians from Persia, their bishops, priests or laymen began visiting them. Most of them were not able to return due to financial difficulties and travelling long distances. The Knanaya people were worshipping
