Christians who do not have noetic prayer are not intrinsically different from believers in other religions. The only factor that makes such Christians different from believers of other religions is that these Christians intellectually believe in Christ and merely accept Christian doctrine, while the believers in other religions do not accept Christian doctrine. But such Christians do not gain anything from this kind of intellectual faith, because it does not heal them or purify their hearts from the passions.
In terms of healing the human personality, they remain without benefit and with behavior that does not differ from that of non-Christians. This can be seen in their way of life.
Consider an Orthodox Christian whose soul is sick, but who not only fails to struggle to be healed, but does not even imagine that the Church has an effective therapeutic strategy for curing his sickness. What is the difference between such a nominal Orthodox Christian and a Muslim, for example? Does doctrine make him different? But what good is doctrine when it is not used as a pathway towards healing? What good is doctrine when it is merely kept hung up in the closet so that it can be worshipped? In other words, what is the point of worshipping the letter of the dogma and ignoring its spirit, hidden within the letter?”
