Thomas More, Chancellor to Henry VIII, executed for his refusal to call Henry the Supreme Head of the Church, and later made a saint by the Catholic Church has this prayer dedicated to him. Every lawyer — religious or not — should live by it.

May I be able in argument, accurate in analysis, strict in study, correct in conclusion, candid with clients, honest with adversaries, faithful in all details to the profession. May I listen patiently and with kindness to my client's tales.  May I not, to win a point, lose my soul.

May others find in me what they have a right there to see - honour and humility, cheerfulness and charity, an approach to wisdom, counsel, and sound consolation
