On July 10, 2025, Pope Leo XIV officially erected the Catholic Diocese of Kapsabet, making it the 28th Diocese in the country. The new ecclesiastical jurisdiction has been carved out of the Catholic Diocese of Eldoret and will encompass the entire Nandi County.
The Holy Father has appointed Rt. Rev. John Kiplimo Lelei, the current Auxiliary Bishop of Eldoret, as the founding bishop of the Diocese of Kapsabet, at the same time releasing him from the titular see of Monte di Numidia.
