Maramon Convention is the largest annual Christian convention in Asia. The convention is held on the sandbanks of river Pamba near Kozhencherry. It has become one of the major Christian conventions in the world. By the end of 19th century C.E, 12 persons formed the Mar Thoma Evangelistic Association and when the renaissance movement led by Abraham Malpan and Kaithayil Geevarghese Malpan failed to take off, two famous evangelists from Ceylon came to Kerala and gave a sermon. It is held in Pathanamthitta district and is conducted by the Mar Thoma Evangelistic Association (META), the missionary wing of the Mar Thoma church.
Usually held in the month of February, the convention is attended by thousands from India and abroad. As many as 30,000 people participate in the eight-day convention. This was the inspiration for other sects to conduct retreats and prayer meetings. This also led to the formation of other permanent convention centres. Missionaries of the Evangelistic Association also come and share their experiences with the believers. The convention was first held in the year 1895 for a period of eight days. The sandbanks of river Pamba literally turn into an ocean of humanity with the believers from different churches thronging here to take part in this ecclesiastical summit.
