This Bible verse is on their flyer:
Ephesians 5:6 ...for because of these things cometh the wrath of God upon the children of disobedience.
Cherrypicking verses out of the Bible with no context is what crackpot groups like this use to suck in ignorant followers. That is not even the entire 6th verse!
Just going back to Ep. 4:29 will reveal a totally different message. (forgive me for quoting NT scripture but these kind of Christians drive me crazy)
29 Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
31 Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice:
32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
1 Be ye therefore followers of God, as dear children;
2 And walk in love, as Christ also hath loved us, and hath given himself for us an offering and a sacrifice to God for a sweetsmelling savour.
3 But fornication, and all uncleanness, or covetousness, let it not be once named among you, as becometh saints;
4 Neither filthiness, nor foolish talking, nor jesting, which are not convenient: but rather giving of thanks.
5 For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God.
6 Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience.
7 Be not ye therefore partakers with them.
8 For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light
Of course homosexuality is an abomination but please leave the wrath to God.
