Catechists perform an important job on our Church. Those who do it well do it from the deep well the Faith gives them and they do it with conviction and humility, from weakness and humanity powered by the Holy Spirit. They create relationships which tell others about Jesus as much or better than their words do.
They say that if you want to learn something, teach it. It starts with a desire to share but moves beyond that to a personal deepening of one's relationship with Jesus which only fuels the desire to share it more.
The task of coherently spreading knowledge of God into the hearts of others is on going and demanding but the people who rise to do it always have my admiration and prayers.
Who indeed is the victor over the world but the one who believes that Jesus is the Son of God?
This is the one who came through water and Blood, Jesus Christ, not by water alone, but by water and Blood. The Spirit is the one who testifies, and the Spirit is truth. So there are three who testify, the Spirit, the water, and the Blood, and the three are of one accord. If we accept human testimony, the testimony of God is surely greater. Now the testimony of God is this, that he has testified on behalf of his Son. Whoever believes in the Son of God has this testimony within himself. Whoever does not believe God has made him a liar by not believing the testimony God has given about his Son. And this is the testimony: God gave us eternal life, and this life is in his Son. Whoever possesses the Son has life; whoever does not possess the Son of God does not have life.
I write these things to you so that you may know that you have eternal life, you who believe in the name of the Son of God.
-- 1 John 5:5-13
