Etymology of Ayyavazhi
This etymological topic deals with the origin, regeneration and evolution of various names by which Ayyavazhi is referred or identified throughout the period of Ayyavazhi history. Though the name 'Ayyavazhi' is commonly used and the most accepted term to represent Ayyavazhi there are other terms too which are used to refer it.
The exact origin of the name Ayyavazhi is not known. The various theories on its derivation include:
- Ayya's path
- from the direct synonymous derivation, which takes Ayya as a noun (naming word) of Ayya Vaikundar.
- Path of Father
- from the local spoken-Tamil language Ayya (father) + vazhi (path). This meaning, derived from Tamil, is most commonly used as 'ayya', and means 'dear father'.
- The ultimate truth of Master
-  from Tamil Ayya (Master) + vazhi (the ultimate truth) is derived from the literary usage of the words.
- Religious system of Guru
- from Tamil Ayya as (Guru) + vazhi (religious system - vazhibadu in Tamil).
- Way of attaining the sacred feet of God
- Ayya as (God) + vazhi (way to unify)
The synonymous versions of the phrase are virtually unlimited, because the usage of the word 'Ayya' in Tamil varies widely. It is used to convey the words father, guru, the superior, a person of dignity, respectable one, master, the king, the teacher, preceptor, etc. The word 'vazhi' in Tamil can mean the way, a course of conduct, manner, method, mode, cause, antiquity, succession, religious system, reason, and so on.
This was a name given to Ayyavazhi during the late 19th century by the London Missionary Society Missionaries who is of negative views over Vaikundar. So they pour hatred on both Vaikundar and the belief centering him. They, however, recognise Ayyavazhi as an alternate religious phenomenon against or outside Hinduism. They referred to Ayyavazhi as Muttukutyism, being mistaken that Muttukutty is the one who believed as a god-incarnate by the followers.
It was in the village comprising this (Thamaraikulam) section that the gospel gained its earliest conquests in South Taravancore. Progress was rapid. Congregation were formed and adherents come over in great numbers. In 1821 there were upwards of 1200 converts in these place. It seemed as if the whole population would soon be brought under the influence of the cross. But a terrible check was given to our operations by the rise of Muthukuttyism. ... shrines rose, rites and ceremonies are initiated, temples were dedicated and lastly a car festival was instituted at Kottayady to which thousands are annually drawn from the towns and villages far and near. This cunning contrivance of Satan has much impeded our progress in these parts and s still a great power of darkness against which we have to wage unceasing war. Our weapon are mighty through god, to the pulling down of strongholds. We have truth on our side against which neither Muthukuttyism nor any other gate to hell shall prevail. All we need is more life in these churches...
