Christianity is the predominantreligion in Tonga, withFree Wesleyan Church of Tonga having the most adherents.[2][4]
TheConstitution of Tonga establishesfreedom of religion, which is respected in practice by both the government and general society, although there are some laws which restrict commerce and broadcast media in accordance with Christian religious norms.
Tongans are ardent churchgoers.Church service usually follows a call and response structure. Singing in the church is often donea cappella. Although a church attends primarily to the spiritual needs of the population, it also functions as the primary social hub.
Sunday is celebrated as a strict sabbath, enshrined so in the constitution, and despite some voices to the opposite, the Sunday ban is not likely to be abolished soon. No trade is allowed on Sunday, except essential services, after special approval by the minister of police. Those that break thelaw risk a fine or imprisonment.[5]
Along with others fromOceania, some Tongan Christians have attempted to develop their own uniquetheology which addresses the contextual questions offered by people of thePacific. This includes thecoconut theology of the MethodistSione 'Amanaki Havea or theincarnational theology of the CatholicBishop of TongaPatelesio Finau.[6]

The constitution of Tonga establishes the freedom of religion, with the qualification that this freedom is not used to "commit evil" or to otherwise violate the law. The constitution forbids commercial transactions on Sundays in accordance with theChristian Sabbath, although the tourism industry is granted some exceptions from this rule.[23]
Religious organizations are not required to register with the government, but may do so in order to receive tax exemptions, the right to issue legally recognized marriage certificates, and other privileges. Foreign missionaries may operate in the country without special restrictions.[23]
Public schools may choose to include up to an hour of religious education per week; students are required to attend religious education courses pertaining to the religion that they profess. Many religious organizations operate private schools.[23]
The government allows religious organizations to broadcast programming onTV Tonga andRadio Tonga, officially with the restriction that they must limit their messaging to be "within the limits of the mainstream Christian tradition". Despite this restriction, in the past theBaháʼí Faith community has televised programming, although the community has since discontinued this program. As of 2017, there have been no reports of the government denying requests for air time from any religious organization.[23]
