Catholic theology
Catholic belief holds that the church exists both on earth and in heaven simultaneously, and thus the Virgin Mary and the saints are alive and part of the living church. Prayers and devotions to Mary and the saints are common practices in Catholic life. These devotions are not worship, since only God is worshiped. The church teaches that the saints "do not cease to intercede with the Father for us. ... So by their fraternal concern is our weakness greatly helped."
Roman Catholic (term)
Orthodox Christians sometimes use the term "Uniate" (occasionally spelled "Uniat") to describe the Eastern Catholic churches which were previously Eastern or Oriental Orthodox, although some consider this term derogatory. Official Catholic documents no longer use the term, due to its perceived negative overtones. In fact, according to John Erickson of Saint Vladimir's Orthodox Theological Seminary, "The term 'uniate' itself, once used with pride in the Roman communion, had long since come to be considered as pejorative. 'Eastern Rite Catholic' also was no longer in vogue because it might suggest that the Catholics in question differed from Latins only in the externals of worship. The Second Vatican Council affirmed rather that Eastern Catholics constituted "churches", whose vocation was to provide a bridge to the separated churches of the East."
"Note: Romanian, Greek, and Ukrainian statistics may be translations that reflect the usage of "Roman Catholic" in the original languages, and may not necessarily reflect the prevailing use of the term among native English speakers."
