I'm generally a bit sceptical of recipes for success that are applied by age group. This for Gen X or Y, that for Millennials...
But I absolutely agree with author Addie Zierman that the 5 things named here are the kinds of things that would not appeal to someone exploring church. She says they would scare off Millennials. I would go further: I think they would scare off anyone in their right mind, however old or young they may be. The conclusion - "choose honesty over cliché" might apply to people generally.
