Thanks for defining Christianity, offering candles and flowers is one's way of thanking Jesus or the saints (not the lifeless statues, as you say) for favors received. The priest has not encouraged it because it brings in money. I for one would prefer to put in money in the church boxes instead of the flowers and candles, as the church needs the money for its upkeep. Christianity for me does not mean just loving your brother or sister, it is forgiving my enemy. May Christ forgive you. Michael.
