The textual issue aside. Here’s a question for you all.
When the author of Ephesians writes, “τοῖς ἁγίοις τοῖς οὖσιν ἐν Ἐφέσῳ καὶ πιστοῖς ἐν Χριστῷ Ἰησοῦ,” what does he mean?
Are the recipients “Holy ones who are in Ephesus” and “faithful ones in Christ Jesus” where the καὶ coordinates two complete ἁγίοις and πιστοῖς?
Or are the recipients “Holy ones who are in Ephesus and faithful in Christ Jesus” where the coordinates τοῖς οὖσιν ἐν Ἐφέσῳ with πιστοῖς ἐν Χριστῷ Ἰησοῦ both modifying ἁγίοις ?
Feel free to make your case either way in the comments.
