Letters of Ignatius 15

1None of these things is hidden from you, if you are complete in your faith and love toward Jesus Christ, for these are the beginning and end of life—faith is the beginning and love is the end. The two, found in unity, are God, while everything else follows in their train toward true nobility.

2No one who professes faith sins, and no one who possesses love hates. The tree is revealed by its fruit; likewise, those who profess to belong to Christ will be recognized by their actions. For the Work is not now a matter of profession, but is seen when someone is found in the power of faith to the end.
