Cyrill of Alexandria
It is written, ‘Prepare the way of the Lord’ (Matt. 3:3). This means to be prepared to embrace the principles that Christ sought to establish as righteous; remove your heart from the influence of the law; turn away from the veneration of idols; and set aside thoughts of malice. Make straight the paths of your Lord (Matt. 3:3). For every path that leads to goodness is direct, smooth, and effortless; conversely, the other path is one of corruption, leading those who tread upon it to ruin. Concerning them, it is stated: whose ways are crooked, and who wander in their paths (Proverbs 2:15). Thus, a mind that is straight corresponds to a path that is true and without deviation.
