Familiarization is a double-edged knife. On the one hand it can ease, and on the other it can ruin. It makes things easier if we want to get to know something deeper, it ruins if we consider intimacy as a means of getting acquainted enough and we do not want to go deeper.
In matters of faith this is of great importance, because acquaintance, familiarity with something, must be accompanied by deeper interest and quest. Otherwise the acquaintance stays on the surface, there is no interest in cultivation, and while the right course is from good to better and from mega to major, we become satisfied with the existing acquaintance and soon any progress, any challenge for new steps, falls in the vacuum with the satisfaction that comes from the mentality of “I know and do not need to know anything new”.
The Greeks know Christ as a name and as a form from the depictions of the Church. But we do not know the teaching of Christ adequately, and more importantly we do not care to educate ourselves in hearing and applying the teaching, so, as a result, we lose a lot of capital from the gifts of God. In the latter case, we are not only losing, but gradually immersing ourselves in the pool of unbelief and ultimately infidelity along with individual deprivation and loss of not only material but also indestructible goods.
