2. Concrete Catholicity is pursued best by identifying with a local church, not through reading tons of books, web-sites, or assenting to abstract dogmas.
It is assumed that all churches this side of heaven are growing in maturity, grace, and understanding. After all, Jesus promised to send the Holy Spirit, who would guide us into all truth. However, the temptation is to put the Spirit on our rigid schedule, and expect radical change the day before yesterday. This is especially a problem for young men who read too much theology (like myself). Reading big, fat books does not give you credibility or persuasiveness. Loving your wife as Christ loves the Church and raising godly children is a powerful apologetic. Living as a faithful father is more persuasive than quoting the fathers.
