Why is Sacred Chrism used in Baptism or Confirmation?

Roman Catholic AnswerFor a complete description of Sacred Chrism see the article at the link below. This is an excerpt from The Catholic Encyclopedia:If it be asked why chrism has been thus introduced into the functions of the church liturgy, a reason is found in its special fitness for this purpose by reason of its symbolical significance. For olive-oil, being of its own nature rich, diffusive, and abiding, is fitted to represent the copious outpouring of sacramental grace, while balsam, which gives forth most agreeable and fragrant odours, typifies the innate sweetness of Christian virtue. Oil also gives strength and suppleness to the limbs, while balsam preserves from corruption. Thus anointing with chrism aptly signifies that fulness of grace and spiritual strength by which we are enabled to resist the contagion of sin and produce the sweet flowers of virtue. "For we are the good odour of Christ unto God" (2 Corinthians 2:15).
