In Ephesians 5:1-2 Paul called on the one who is in Christ to “imitate God” by living out their life in the same sacrificial love with which Christ loved us when he gave up his life on the Cross as a “fragrant offering” to the Lord. Although there is no other place in the New Testament where the believer is called to imitate God, here Paul says we imitate God by living in the pattern of Christ’s self-sacrificial love.
Sexual immorality and impurity seem obvious, but Paul mentions greed in the same line. This is similar to 4:19, all three words appeared there as well.
Immorality is a generic word (πορνεία) that covers a wide range of sexual sin, often called “fornication.” As the Supreme Court justice Potter Stewart once described pornography, “I cannot define it, but I know it when I see it.”
Impurity (ἀκαθαρσία) refers to anything which is filthy or corrupting, so the word is used in ethical texts for sexual sins. In 1 Enoch 10:11, for example, the sin of the angels is impurity. Paul often links filth and corruption, see 2 Cor 12:21, for example. but he does not need to define them since the meaning would be obvious to the reader.
By translating πλεονεξία as covetousness (ESV) or greed (NIV), the reader may think only of financial greed, and then wonder why greed is connected to two words which generically describe sexual sins. In classical Greek, however, this word refers to “vice pure and simple” and is among “the three most disgraceful things” (BDAG).
These vices are not even to be mentioned (looking forward to the next line), because they are not fitting for “the saints.” The verb Paul uses (ὀνομάζω) is rare, and in the passive (as it is here) can have the sense of “be known.” In Romans 15:20, for example, Paul’s desire is to preach the Gospel where “Christ is not known.” Paul’s exhortation here is that the believer is better off ignorant of these things!
For example, I do not need to know the details or experience the details personally to know that heroin addiction is not a good lifestyle choice. In the same way, Paul is simply saying the Christian does not need to dwell on the details of immorality in order to know it is not appropriate for the Christ. This has obvious implications for pornography, but also for other entertainment choices (film, music, literature). Although I would not advocate only Christian entertainment, there are some forms of entertainment which “are not fitting.”
The reason there is no need to know these things is that they are not fitting for those who are being built into a holy Temple of God (2:20). Paul is developing a metaphor of a Temple, and individual members of the Body of Christ are part of that temple. Some behaviors simply “do not fit” into that Temple. Most Christians who have unsaved friends have experienced have experienced some sheltering, “we cannot watch that movie because Bob is a Christian.”
Paul also refers to obscenity, foolish talk coarse joking are three terms found only here in the NT and are fairly self-explanatory (cf. 4:29 and Col 3:8). Filthiness (αἰσχρότης) refers to obscene talk or “obscenity,” or behavior which “behavior that flouts social and moral standards” (BDAG). Foolish talk (μωρολογία) does not refer to stupidity, but intentionally foolish speech, even “foolish gossip” (EDNT, following TDNT, 4:844; cf. 2 Tim 2:23; Titus 3:9). The word had a positive sense in earlier Greek literature (“adroitness of speech”), but in this context the noun is obviously negative. Crude joking (εὐτραπελία) or “base jesting,” or somewhere between “the extremes of buffoonery (βωμολοχία) and boorishness (ἀγροικία)” (BDAG).
Paul is in line with Jewish wisdom literature, and there is a remarkable parallel in the Dead Sea Scrolls Community Rule (1QS 10.21-25):
1 QS 10.21-25 I shall not retain Belial within my heart. From my mouth shall not be heard 22 foolishness or wicked deceptions; sophistries or lies shall not be found on my lips. The fruit of holiness will be on my tongue, profanity 23 shall not be found on it. With hymns shall I open my mouth and my tongue will continually recount both the just acts of God and the unfaithfulness of men until their iniquity is complete. 24 I shall remove from my lips worthless words, unclean things and plotting from the knowledge of my heart. With prudent counsel {I shall hide} /I shall recount/ knowledge, 25 and with discretion of knowledge I shall enclose him with a solid fence to maintain faithfulness and staunch judgment according to the justice of God.
These kinds of people will not inherit the kingdom of God. Although Paul says a similar thing in 1 Corinthians 6:9-11 (the immoral will not inherit the kingdom), it is surprising to find Paul using kingdom of God as more or less equivalent to salvation.
I find this all very convicting. It seems obvious the Christian ought to avoid obvious immoral things (and there are good psychological reasons for anyone to avoid the things which are corrupting). But it is quite easy for me to tell a flippant joke or engage in gossip. For Paul, the Christian needs to be wise in their speech and not “talk like the world.” This does not mean Christians have to be boring, but it is very easy to get a laugh with a crude joke.

The first words of this long sentence (124 words!) are “and you…” The pronoun “you” is accusative and the object of the verb “made alive” in verse 5. The content between the verb and the object is the state of the Gentile believers before coming to Christ. Despite the fact were dead in our sin, God made us alive in Christ!
Timothy Gombis develops this view of powers and dominions as the main thesis of his book The Drama of Ephesians.This book argues Paul is using imagery of spiritual warfare drawn form the Hebrew Bible to describe what Jesus has done on the cross. Using Ephesians 1:20-23, for example, Gombis points out that Paul says Jesus was vindicated by being raised to the right hand of the father in heaven.
