Today is Pentecost Sunday, celebrating the birthday of the Church. From the second reading of 1 Corinthians, Paul writes: In one Spirit we were all baptized into one body, whether Jews or Greeks, slaves or free persons, and we were all given to drink of one Spirit. The Holy Spirit is indeed the one who can unify all Christians and of whom our spirits need to drink to get sanctified. If your heart is not on fire yet, ask the Holy Spirit to zap you and he'll do just that – I am speaking from personal experience. The Christian life comes alive once you are aware that the Spirit does dwell within you.
