After returning to Kimberly in South Africa, Alexander traveled throughout South Africa and established parishes wherever he found interest. His [[missionary]] activities also took him into countries outside of the Republic of South Africa, to Kenya, Uganda, and Rhodesia. Soon, [[Christopher Reuben Spartas|Reuben Spartas]] in Uganda contacted Alexander in his search for Orthodoxy. This led to Alexander traveling to Uganda in October 1931 and his ordaining Reuben Spartas and Obadiah Basajjikitalo as [[priest]]s in 1932.
When, in May 1935, Alexander wrote to Archbishop Isidore of the Greek Orthodox [[Archdiocese of Johannesburg and Pretoria|Archdiocese of Johannesburg]] asking for letters of introduction to Fr. [[Nikodemos Sarikas]] of Tanganyika and the [[Church of Jerusalem|Patriarch of Jerusalem]], Abp. Isidore replied that he should instead visit the [[Church of Alexandria|Patriarch of Alexandria]]. Alexander arrived in Kenya on [[November 18]], 1935, and founded a [[seminary]] at Gituamba with eight students
. In June 1937, he ordained two of his students as priests and two as deacons and returned to South Africa. In 1941, the African Orthodox Church in South Africa received government recognition.
After the death of McGuire in late 1934, the relationship between the South African and the American churches continued to be amicable under a new patriarch in America .
In 1960, two bishops from the American branch of the AOC, including AOC Patriarch James I, were invited to South Africa by Alexander, now 78 years old, to consecrate two new bishops to provide for an established succession. Shortly after the consecration, James I requested Alexander's resignation, which he refused to do. While in dispute, James and his bishop Motsepe died. Although Alexander apparently reconciled with the new AOC patriarch, Peter IV, Alexander was [[deposition|deposed]] in 1963.
