I hardly think half of priests are sexual predators. I was raised Catholic and have been around priests since birth. I've confessed to them, received the sacraments from them, been taught by them and socialized with them. I've not met any accused of criminal acts.
The real problem of the deep malaise of our priesthood aside, I am Catholic for many reasons. Yes, it is the religion of my ancestors and this increases the beauty of this faith for me. My sense of spiritual awe, love of God, Christ His Son, love of my fellow human beings, as well as my conscience, were all formed by a host of wonderful, loving, self sacrificial people- most of whom were lay people (and mostly women, at that). Priests are not the only source of vitality in the Catholic faith- far from it!
I am Catholic because of tradition and history. I am Catholic because Christ established the Church as His Mystical Body. I am Catholic because of the Most Holy Eucharist, which is the Lord's gift of His Body and Blood. I am Catholic because of the Holy Mass and the sacraments, for the prayers of the liturgy and devotions like Benediction, the Stations of the Cross and the Rosary. I am Catholic for the ongoing presence of the Virgin Mary in my life.
I am Catholic because I believe incarnate, crucified Love is at the heart and pulse of the Tradition. However much this Love might be obscured, I know that, through and in the Church, I have met it, received it, am nourished by it.
