Heterodoxy
Many Roman Catholics profess some heterodox views, either on doctrinal or social issues. For example, the orthodox Catholic position on unbaptized infants is that their fate is uncertain, and "the Church can only entrust them to the mercy of God" (Catechism of the Catholic Church 1261). A heterodox Catholic might profess the belief that unbaptized infants are offered the option to accept or deny salvation by God at their judgment. The belief is not orthodox, as the Church does not profess a belief as to what happens to unbaptized infants; however, it is also not heresy, as the Church accepts that such a scenario might be possible. By contrast, a denial of the doctrine of "Original Sin" (thereby negating the necessity of baptism for children) or Papal Infallibility -- would be labeled heretical.
