This day the earth became Heaven for us. Not because the stars descended from the heavens to earth, but because the apostles ascended to Heaven by the grace of the Holy Spirit, which was now abundantly poured forth, and so the whole world was transformed into heaven; not because human nature was changed, but because there was a change in the direction of the will. For there was found a tax-gatherer, and he was transformed into an evangelist. There was found a persecutor, and he was changed into an apostle. There was found a robber, and he was led into Paradise. There was found a prostitute, and she was made the equal of virgins. There were found wise men, and they were taught the Gospels. Evil fled away, and gentleness took its place. Slavery was put away, and freedom came in its stead. And all debts were forgiven, and the grace of God was conferred. Therefore Heaven became earth.
But if you are fearful of becoming self-righteous from working for your own salvation, or afraid of being overcome by spiritual pride, examine yourself and observe that the person who is afraid of becoming self-righteous suffers from blindness. For he does not see how self-righteous he is.
If we fervently desire holiness, the Holy Spirit at the outset gives the soul a full and conscious taste of God’s sweetness, so that the intellect will know exactly of what the final reward of the spiritual life consists.
And the opinion, extremely popular in our times, that 'it's all the same which church you go to; after all, God is one' is in agreement with this tendency. Yes! God is one, but, you know, He also gave us one faith; He created one Church for us, not many different faiths and 'churches.' This is confirmed by the holy Apostle Paul when he says, 'One Lord, one faith, one baptism, one God and Father of all,' and so we Christians should form 'one body and one spirit,' as we are called to 'in one hope of our calling' (Eph. 4:4-6). If there is only one true faith and only one true Church, then as a consequence all other faiths and 'churches' are false, not true. How then can anyone say that all faiths and 'churches' are of equal value and that 'it is all the same which church you go to.' Therefore one can and must speak not of the ecumenical unification of everyone for the creation of some new Church, but only of the restoration of union between all who have fallen away and the one true Church of Christ to which Christ the Savior Himself gave the great and sure promise that 'the gates of hell will not prevail against it' (Matt. 16:18).
Holiness is not simply righteousness, for which the righteous are rewarded with blessedness in the Kingdom of God; rather, it is such a height of righteousness that people are so filled with the grace of God that it flows from them even upon those who associate with them. Great is their blessedness, which proceeds from their direct contemplation of the glory of God. Being filled also with love for men, which proceeds from love of God, they are responsive to men's needs, and at their entreaties they act as mediators and intercessors for them before God.
