There is nothing more poisonous or ruinous for the spirit of Christian life than such learning and an exclusive concern for it. It casts one straight into coldness and then one can keep one forever in it, and sometimes it also adds to this an immoral life, if there are conditions which are favorable for this. The second thing to which attention should be given is the spirit of the instruction or of the attitude towards the objects of study. It should be placed as an unfailing law that every kind of learning which is taught to a Christian should be penetrated with Christian principles and, more precisely, Orthodox ones. Every branch of learning is capable of this approach, and it will be a true kind of learning only when this condition is fulfilled.
Christian principles are true beyond doubt.
Therefore, without any doubting, make them the general measuring stick of truth. On the contrary, we have a single spirit. It receives learning and is imbued with its principles just as it receives faith and is penetrated by it. At the same time, the sphere of truth is one. If instruction will be conducted in this manner, so that faith together with life in the spirit of faith might dominate in the attention of pupils, both in the manner of studying and in the spirit of instruction, then there is no doubt that the principles placed in childhood not only will be preserved, but will increase, be strengthened, and come to a corresponding maturity.
