V. “And Forgive Us Our Trespasses, as We Forgive Those Who Trespass AGAINST US”

From The Catechism of the Catholic Church

2842
This “as” is not unique in Jesus’ teaching: “You, therefore,
must be perfect, as your heavenly Father is perfect”; “Be merciful,
even as your Father is merciful”; “A new commandment I give to you,
that you love one another, even as I have loved you, that you also love one
another.”¹³⁹ It is impossible to keep the Lord’s commandment by
imitating the divine model from outside; there has to be a vital participation,
coming from the depths of the heart, in the holiness and the mercy and the love
of our God. Only the Spirit by whom we live can make “ours” the same
mind that was in Christ Jesus.¹⁴⁰ Then the unity of forgiveness becomes
possible and we find ourselves “forgiving one another, as God in Christ
forgave” us.¹⁴¹
