In 1951, [[Archimandrite]] [[Petros (Astyfides)]] arrived in New York at the invitation of [[Arsenios Saltas]], whom he understood to be the Greek Old Calendarist [[bishop]] of America. Soon learning that this was not the case, Archimandrite Petros resolved to return to Greece. However, a number of Greek Old Calendarist families in Queens persuaded him to begin services for them, and by 1954 [[Saint Markella's Cathedral]] was established.
Archimandrite Petros began to gather various independent parishes until a diocese was formed. During this time, he was under the [[Metropolia]] and then the [[ROCOR]]. Two ROCOR bishops
--[[Seraphim]] and [[Leonty]] --[[consecration of a bishop|consecrated]] him to the episcopacy in November 1962. This consecration was not technically canonical, as it was done in secret ; however, by 1969 the ROCOR had recognized the necessity of this and other Old Calendarist consecrations, and recognized the Greek Old Calendarist bishops. At this time, Metropolitan Petros joined with the Synod in Greece officially.
