Sunday Adelaja (Russian, Belarusian and Ukrainian: Сандей Аделаджа) is the founder and senior pastor of the Embassy of the Blessed Kingdom of God for All Nations, an evangelical-charismatic megachurch and a Christian denomination in Kyiv, Ukraine.

In 1986, after graduation, Adelaja left Nigeria because he received a scholarship to study journalism at the Belarusian State University in Minsk, Byelorussian SSR.

[3][4] He claims he was threatened there by authorities for having a picture of Jesus in his house, but nevertheless, he began Christian activities in Belarus during his studies.

By his own account, he was tipped off that day that he was on a Russian hitlist, and he and his wife immediately drove to Poland, gaining asylum in Belgium later in 2022, where he was resident as of 2024.

[6] In October 2010, Sunday Adelaja was one of the foreigners in Ukraine who were awarded The Most Influential Expats 2010 by the Kyiv Post newspaper.

[30] At the Azusa Street Revival Festival on Saturday April 25, 2009, Sunday Adelaja received the first International William J. Seymour Award.

[34] Adelaja was accused in November 2008 of being involved in the dealings of King's Capital, a financial group led by a former member of his congregation.

Kyiv's Mayor Chernovetsky, himself a church member, had earlier said that Adelaja was not involved in the financial scheme at King's Capital.

[36] In September 2009, the Ministry of Internal Affairs of Ukraine admitted that they had exhausted their possibilities in the criminal case against Sunday Adelaja.

[38] Adelaja considers the police's decision to investigate him for involvement in the financial group's machinations as an implementation of political order.

[6] On 28 December 2008, nine leaders of evangelical churches in Ukraine signed a statement in which they, among other things, dissociated themselves from Sunday Adelaja and his activity.

[39][40] In March 2016, the Russian Union of Christians of Evangelical Faith announced in a press release that Adelaja was in recovery after confessing before a conference of pastors to adultery with women in the church.

[44] The then-mayor of Kyiv, Leonid Chernovetsky, is a member of the Embassy of God, but he was in opposition to the principal actors of the Orange Revolution, including Premier Yulia Tymoshenko.

[45] Adelaja stated about the then candidate in and later winner of the 2004 Ukrainian presidential election Viktor Yushchenko: "He is a committed believer who is serious about his faith, and is influenced by God and the Bible".

[citation needed] During the 2010 president elections Adelaja decided and called all affiliated churches to vote for Victor Yanukovich, the opponent of the "Orange" leaders (Tymoshenko and Yushchenko).

[48][6] At the time of Russia's invasion of Ukraine in 2022, Adelaja believed that he was on a Russian hit-list, a view seen as plausible by the scholar Catherine Wanner.
