It was established in 1642 after Dutch missionaries introduced Protestantism to Sri Lanka. The church has a rich history dating back to the Dutch colonial period and continues to have a presence with over 5,000 members and 31 churches across the country. The church follows Reformed, Calvinist beliefs and has strong relationships with other Protestant denominations both locally and internationally.
