The monotheistic 'gods' of the other major world religions are often aloof figures speaking only through intermediaries, and whose love and grace are based solely on our moral performance. If we keep such deities happy they might be generous, if not.....oblivion.
The true God presented by the great statements of the Athanasian Creed, "Unity in Trinity, and Trinity in Unity", shows us a Triune God in relationship with himself and with us, who acted in unison at the creation of everything, but more importantly acted together to save us his fallen creatures blighted by sin and death. God came to earth in human flesh so we could know the mercy of the Father and have a relationship with him through the shed blood of Christ on the cross, who sent the Holy Spirit to indwell and sanctify us bringing us back from ruin into the light of God's will.
The Father sends, the Son justifies, the Spirit sanctifies, Three Persons in One seeking us out to create a holy people for Himself, one in perfect relationship with their Creator. Not based on moral performance, good works or religious fervour but on the work of God alone whose mercy and grace will never run dry.
In the name of Christ. Amen.
