Maybe a good place for this thread to go is to make a new list based on St Gregory's orations.
1. don't delight in profane babblings and "knowledge so called" or strife of words (Would this include delighting in modern commentators who themselves show no signs of being enlightened by the Spirit as a way of trying to compensate for our own lack?)
2. don't be obsessed with arguments as a way of showing off your knowledge and skill, or as a way of asserting your opinion
3. Be undergoing purification and have a certain amount of internal peace "It is when we are free from all external defilement or disturbance, and when that which rules within us is not confused with vexatious or erring images"
6. be willing to apply oneself to serious study, don't be a dilettante
7. have a humble and accurate grasp of your own degree of illumination and capacity and don't go beyond this "that the extent to which we may go is that to which we have ourselves advanced, or to which we are advancing"
(This is the really hard one)
8. along with this have the patience and faith to live in ignorance, trusting in the practice of outward forms of religion till the Spirit gives enlightenment (see oration 28.2) (another hard one for those who trust in their minds)
9. remember God at all times, but only discuss theology in due season
10. be living according to the ascetic life of the Church rather then giving free rein to the passions (see list in 27.7)
Here is a start. Maybe others can add more.
"Blessed are the pure in heart for they shall see God"-in this we start to acquire the mind of Christ/mind of the Fathers, are able to "ascend the mount" to one degree or another and in this we go from truth to truth.
"The Orthodox soul is taught by grace to hold fast to the Lord and his most Holy Mother, and our spirit rejoices in the contemplation of God Whom we know. But we can only know God by the Holy Spirit, and the proud man who aspires to know the Creator with his intelligence is blind and stupid. With our minds we cannot even come to know how the sun is made; and if we beg God to tell us how He made the sun the answer rings clear in the soul: 'Humble thyself and thou shalt know not only the sun but the Creator of the sun.'" St Silouan the Athonite
