A summary of Patristic thought

Here is an excellent summation of the piety and theology of the Fathers: "To receive mystically the Trinity and share in God's own triune life by following the commands of Christ, was for the Church Fathers the very purpose of human existence." [A. Edward Siecienski, The Filioque (OUP, 2010), vi].

Rightly Augustine would want to add the phrase "by grace" to this statement: "by grace share in God's own triune life."
