Great is this mystery, and great is the mercy of God towards man. If all the people of the earth knew how deeply the Lord loves man their hearts would be filled with love of Christ and Christ’s humility, and they would seek to be like Him in all things. But man cannot do this by himself, for it is only in the Holy Spirit that he can become like unto Christ. Man that is fallen purifies himself through repentance, and is made new by the grace of the Holy Spirit, and in all things becomes like unto the Lord.
Blessed are the pure in heart, for they shall see God. Everything we do, our every objective, must be undertaken for the sake of this purity of heart. This is why we take on loneliness, fasting, vigils, work, nakedness. For this we must practice the reading of the Scripture, together with all the other virtuous activities, and we do so to trap and to hold our hearts free of the harm of every dangerous passion and in order to rise step by step to the high point of love.
Even if we have thousands of acts of great virtue to our credit, our confidence in being heard must be based on God's mercy and His love for men. Even if we stand at the very summit of virtue, it is by mercy that we shall be saved.
If you examine your life well, you will find many instances when God showed His unmistakable mercy to you. Trouble was brewing, but it passed you by for some reason. God delivered you. Acknowledge these and thank God, Who loves you.
How can one say that a man has attained purity? - When he sees all men as being good, and when none appears to him to be unclean and defiled - then he is indeed pure in heart.
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).
