October 31, 2017 marked the 500th anniversary of Martin Luther nailing (or mailing) his 95 Theses, and launching what came to be the Protestant Reformation. Since then believers have divided over Scripture, the sacraments (two, four, seven?), and much less serious issues. So what does this mean, and why should we care? The links below (mostly from First Things) hopefully help you answer some of those questions. For my some of own thoughts on unity in truth, please also see what I believe. And continue to pray and into the unity for which Christ died.
Holy Father, sanctify us in the truth of your word. Grant us faith in your wisdom and not our own, that we may all be one, just as you are in Christ and Christ in you, that we also may be in you—one body.
Help us, Lord, to keep the unity of the Spirit in the bond of peace, that the world may believe that you have sent your Son and loved us even as you loved him.
Keep before us, O God, our hope in Christ alone, that we may be with him where he is—with you—to enjoy the glory and love that is yours from before the foundation of the world.
Wash us in one baptism, feed us from one loaf, refresh us in one cup, that we may praise you with one voice, from one heart, one soul, and one mind.
