As a fourth argument Pictet returned to the baptismal formula of Matthew 28:19— for not only does this passage prove the Spirit to be a person, but also a divine person. For he, in whose name we are baptized, is considered as the author of the covenant of grace, who has authority to institute sacraments for the sealing of that covenant; who can promise and give grace; and whom those that are admitted into the covenant are bound to worship and serve; none of which can be said of any created thing.
