إنجيل توما
Contention exists over whether the "Heliand" is connected to the Gospel of Thomas. The Gospel of Thomas is a Judiac/Christian version of the Gospels found in 1956 that has been attributed the apostle Thomas. Quispel, a Dutch scholar, argues that the "Heliand" author used a primitive "Diatessaron", the Gospel harmony written in 160-175 by Tatian and thus has connections to the Gospel of Thomas by this association. Other scholars, such as Krogmann assert that the "Heliand" shares a poetic style of the "Diatessaron" but that the author may not actually have relied on this source and therefore the "Heliand" would have no association to the Gospel of Thomas.
