Grant, we beseech thee, O almighty God, that, ever meditating on such things as are reasonable, we may, both in word and deed, carry out the things which are pleasing to thee.
--- Collect from the Sixth Sunday after Epiphany
Far from what secular and atheist men would have us believe, the Catholic Faith is reasonable. It all hangs together and flows from one thing to another such that it must be all true or all false (I say this as a convert who came to precisely this conclusion, which was a central point in my conversion). But if it is all false, then whence are we? No, even the conclusion that it is all false is unreasonable; the very existence of man demands a Creator. Let us then meditate on our reasonable faith, which with the grace of God will lead us to do and say things which are pleasing to Him.
