Snorting threats and murder against Christians, misguided Saul is converted to Paul, under the weight of the glory of the Lord and the instantaneous revelation of God’s Truth.

The revelation here is that ours sins affect Christ Himself
(Acts 9:4-5; Catechism of the Catholic Church # 598).

The Church is the Body of Christ. Christ is the Head of the Church. Attacks on the Church, on the people of God, are attacks on Christ, God Himself
(Catechism of the Catholic Church, The Profession of the Christian Faith, Paragraph 2: The Church – People of God, Body of Christ, Temple of the Holy Spirit).
