约翰二书 2 John

约翰二书是新约最短的书信之一，只有十三节，写给「蒙拣选的太太和她的儿女」——许多解经者认为这是对一间地方教会及其成员的亲切称呼。自称「长老」的约翰听见收信人中有人遵行真理，就甚欢喜，于是提笔写下这封简短却分量十足的信。信的主旋律只有一句话：真理与爱必须同行。

信的前半是劝勉：我们要彼此相爱，而爱就是照他的命令行；这不是新命令，乃是从起初所听见、当一直行在其中的道路。后半是警戒：世上有许多迷惑人的出来，不认耶稣基督是成了肉身来的；信徒要小心，不要失去所作的工，对传这等异端的人，连接到家里、问安都不可，免得在他的恶行上有分。

这封短信对今天的读者别有提醒：在「包容」成为口号的时代，爱心若离开真理，会沦为对错谬的纵容；真理若没有爱心，也会变得冷硬伤人。约翰把两者紧紧扣在一起——他「在真理和爱心」里问安，并盼望与收信人当面交谈，「使你们的喜乐满足」。真理是爱得以站立的地基，爱是真理应有的温度。

Second John, only thirteen verses long, is one of the shortest books in the New Testament. It is addressed to "the lady chosen by God and to her children" — a phrase many interpreters take as an affectionate way of speaking to a local congregation and its members. The writer, who calls himself simply "the elder," has heard that some of the recipients are walking in the truth, and his joy spills over into this brief but weighty note. Its melody can be stated in one line: truth and love must walk together.

The first half of the letter is encouragement: love one another — and love means walking in obedience to His commands, not a new command but the one heard from the beginning. The second half is warning: many deceivers have gone out into the world, refusing to acknowledge Jesus Christ as coming in the flesh. Believers must watch out that they do not lose what they have worked for; those who carry this false teaching are not even to be welcomed into the house, lest hospitality become participation in their wicked work.

For readers today, this little letter carries a timely word. In an age when tolerance is the highest slogan, love severed from truth degenerates into indulgence of error; yet truth without love turns cold and wounding. John binds the two tightly together — greeting his readers "in truth and love" and hoping to visit face to face, "so that our joy may be complete." Truth is the ground on which love stands; love is the warmth truth was always meant to have.
