The church doesn’t save, the Lord does. He then adds us to His catholic church. Thank God, He’s God.
Oh, well, at least you’re not one of those Galatians, Romans, or Ephesians, may the Lord bless you with wisdom.
The Lord certainly saves, though His Paschal Sacrifice on the Cross, but it is the role of the Church to lead the flock to salvation.
[16]...flesh and blood hath not revealed it to thee, but my Father who is in heaven. [18] And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it. [19] And I will give to thee the keys of the kingdom of heaven. And whatsoever thou shalt bind upon earth, it shall be bound also in heaven: and whatsoever thou shalt loose upon earth, it shall be loosed also in heaven. (Mt 16)
