Christ the King Parish was founded in 2017 from the merged parish communities of Corpus Christi (Wethersfield), Sacred Heart (Old Wethersfield), Saint Luke (Hartford), and the Korean Catholic Community (Old Wethersfield). The KCC occupied Sacred Heart Church and held a Korean mass on Sundays, while the rest of the parish attended mass at Corpus Christi Church. In 2019, a quasi parish was formed called the Sacred Heart of Jesus Korean Catholic Parish, at which time the Korean Catholic Community no longer belonged to Christ the King Parish.
The founding pastor of the merged parish of Christ the King, is Reverend Nicholas P. Melo.
In the fall of 2018, Corpus Christi Church received much needed renovations, which included a new hard wood floor in the Sanctuary, carpeting in the church aisles, laminate flooring under the pews, and repainting of the stations of the cross, walls, ceiling, chairs and pews. During renovations, Sunday mass was celebrated at St. Luke Church. Parishioners returned to Corpus Christi Church just in time for the Feast of Christ the King, Sunday, November 25, 2018 where Archbishop Leonard P. Blair blessed the new parish at the 10:00 a.m. mass, at which he concelebrated with Christ the King's Pastor, Father Nick Melo and Father George Vellaplackil.
Renovations were completed in early 2019 when three murals were hand painted on the sanctuary walls; behind the presidential chairs; the tabernacle; and the Baptismal font.
