Religion is not a fractional thing that can be doled out in fixed weekly or daily measures as one among various subjects in the school syllabus. It is the truth of our complete being, the consciousness of our personal relationship with the infinite.
I consider it an extremely dangerous doctrine, because the more likely we are to assume that the solution comes from the outside, the less likely we are to solve our problems ourselves.
School has no task more important than to teach strict thought, cautious judgment, and logical conclusions, hence it must pay no attention to what hinders these operations, such as religion, for instance.
A clean confession combined with a promise never to commit the sin again, when offered before one who has the right to receive it, is the purest type of repentance.
