<p>3:15 <i>And let the peace of Christ rule in your hearts- to this you were also called in one body; and be thankful</i>- We are called to the hope of the Kingdom &quot;in one body&quot; (Col. 3:15); all who receive the call of the true Gospel are in the same one body. There is one body, based around sharing the one faith, one hope, understanding of the one Father and Son, having participated in the one baptism (Eph. 4:4-6). So whoever believes the doctrines of the basic Gospel and has been baptized and walks in Christ, we have a duty (and should have a desire) to fellowship. The need for unity amongst us is so very often stressed (e.g. 1 Cor. 1:10; Rom. 15:5,6; Phil. 2:2; Eph. 4:31,32; Col. 3;12-15).</p>
