Are the Sacraments Life-Giving?

QUESTION: I have recently heard a preacher describe the sacraments as "life-giving." Is this correct?

ANSWER: They are not the source of life, but rather the means of grace through which, when used with faith in Christ, the Holy Spirit may impart and sustain life. Baptism is the outward sign of the Spirit's inward work The Lord's Supper is a memorial of Christ's great love manifested in voluntarily dying for us. Whatever brings this event vividly to the mind of the believer is a means of grace. We should beware of resting in the symbol instead of the thing signified. Thousands of ceremonialists are trusting for salvation in symbols instead of the Savior — in the shadow instead of the substance. The sacraments alone, though administered by priests who claim to be ordained by bishops in succession back to the apostles, are not saving. Only Christ saves.

Saved Without Baptism?

\QUESTION: How can the Friends or Quakers be saved when they do not believe in baptism?

ANSWER: It is not a saving ordinance, but a willful neglect of it indicates a spirit of disobedience which is a bar to salvation. But the Friends have no such disobedient spirit. Their difficulty is not in their hearts but in their heads. They believe in baptism, not water baptism, but that of the Holy Spirit, the reality of which water baptism is only a symbol. They say, "Why should I be concerned about the shadow while I have the substance?" Let us be charitable toward the mistake of the Christians.
