No ignorance of truth is a personal sin before God, except that ignorance which springs from personal sin. - Henry Edward Manning

There are only two centres, God and ourselves; and we must rest on one or on the other.

As a dogma, theologians teach that many belong to the Church who are out of its visible unity; as a moral truth that to be out of the Church is no personal sin, except to those who sin in being out of it. That is, they will be lost, not because they are geographically out of it, but because they are culpably out of it.

Twenty errors in practice are as nothing compared with one error in principle. Twenty errors in practice may be corrected, and the twenty-first may never be committed; but one erroneous principle is like a damaged wheel in a machine. It can never work correctly afterwards. One speculative error will produce an infinite series of practical errors. The series is inexhaustible, until the machine itself is either amended or destroyed.
