“If you want to be the Lord’s disciple, you must take up your cross and follow the Lord. Are you hesitating about crafts, businesses and professions for the sake of children or parents?
The proof that family as well as crafts and business are to be left for the Lord’s sake was given us when James and John were called by the Lord and left both father and ship.” (cf. Luke 5:1-11)
Tertullian of Carthage (c. 155-225) from On Idolatry 12.
