Really, Elaine?   I am a cradle Catholic Christian via the waters of baptism and the promises of the Creed.   The words 'orthodox' and 'heterodox' were/are nowhere to be found.  There was not then,  nor is there now,  any hair-splitting within the sacrament over who is/was 'authentic' or 'real'.      The tribal/cultic purity tests being imposed by a certain faction within the RCC is,  as one bishop recently wrote,  a cancer on our Church.  The tired, tribal talking points are not helpful.   Leave it to our Lord to preside at the Particular Judgment,  not the rightwing noise machine of the Church.
