<p>1:2 <i>To the saints and faithful brothers in Christ that are at Colosse</i>- This doesn't refer to two tiers of believers in Colosse but rather reminds them that every believer is a saint. In both Judaism and paganism there was a tendency to consider some believers to be in a 'super' category. Paul carefully debunks that concept.</p><p><i>Grace to you and peace from God our Father and the Lord Jesus Christ</i>- This is no mere standard literary introduction. God's grace and subsequent peace was willed and prayed for by Paul to come upon his audience, and prayer for third parties indeed makes a difference.</p>
