The Holy Father's offer of a Personal Ordinariate for Anglicans entering into full communion with the Catholic Church is a generous and pastoral response to the desire of Anglicans for unity with the See of Peter.
It represents the fruit of earlier discussions (the Malines Conversations and ARCIC, for example), and provides the natural home within the Catholic Church, for those members of the Anglican tradition who have hoped and prayed, since the foundation of the Oxford Movement and before, for the reunion of Anglicanism with the Catholic Church.
Although members of the Personal Ordinariate of Our Lady of Walsingham are generally received in groups, this is not necessarily the case, and even those being received in groups must make an individual petition and profession of faith.
That said, it is still possible for any non-Catholic to be received into the full communion of the Catholic Church through their geographical parish or diocese.
