Old Testament and Church Ministries in Two Ecumenical Dialogues

Abstract: To understand any church institution as founded by Jesus, one must take account of its relationship to his work of bringing the Old Testament revelation and its institutions to their eschatological realization. A sample of the work of recent ecumenical dialogues (BEM and the international Lutheran– Roman Catholic document on church and justification) shows that their discussions of church institutions have failed to do this adequately. This failure has complicated the efforts at unity to which these dialogues intend to contribute. Attention to the Old Testament roots of church institutions can help ecumenical ecclesiology to focus better on some important issues.     

Does the "eyes lead the hand" principle apply to reach-to-grasp movements evoked by unexpected balance perturbations?

A fundamental principle that has emerged from studies of natural gaze behavior is that goal-directed arm movements are typically guided by a saccade to the target. In this study, we evaluated a hypothesis that this principle does not apply to rapid reach-to-grasp movements evoked by sudden unexpected balance perturbations. These perturbations involved forward translation of a large (2 × 6 m) motion platform configured to simulate a “real-life” environment. Subjects performed a common “daily-life” visuo-cognitive task (find a telephone and make a call) that required walking to the end of the platform, which was triggered to move as they approached a handrail mounted alongside the travel path. A deception was used to ensure that the perturbation was truly unexpected. Eleven of 18 healthy young-adult subjects (age 22-30) reached to grasp or touch the rail in response to the balance perturbation. In support of the hypothesis, none of these arm reactions was guided by concurrent visual fixation of the handrail. Seven of the 11 looked at the rail upon first entering the environment, and hence may have used “stored” central-field information about the handrail location to guide the subsequent arm reaction. However, the other four subjects never looked directly at the rail, indicating a complete reliance on peripheral vision. These findings add to previous evidence of distinctions in the CNS control of volitional and perturbation-evoked arm movements. Future studies will determine whether similar visuo-motor behavior occurs when the available handhold is smaller or when subjects are not engaged in a concurrent visuo-cognitive task.     

CATECHIZING THE HEAD AND THE HEART: AN INTEGRATED MODEL FOR CONFIRMATION MINISTRY

In catechesis for adolescents seeking confirmation in the Roman Catholic Church, a dualistic bias unconsciously dichotomizes objective doctrine and subjective psychology. This is problematic because if a catechist does not communicate mind‐independent truth, no seed of Catholic faith will have been planted in a student. At the same time, if a catechist does not affirm a student's subjectivity, the seed cannot find receptive soil. I believe the key to integrating these intellectual and affective elements – the head and the heart – lies in the link between what Bernard Lonergan calls authentic subjectivity and objectivity. Catechists can appeal to this link by embracing the moral responsibility to ‘know our knowing,’ becoming aware of our dualistic bias and judging our faith experiences according to objective standards of knowledge.     

Intracerebroventricular Administration of Mineralocorticoid Receptor Antisense Oligonucleotides Attenuates Salt Appetite in the Rat

The anterior ventral third ventricle (AV3V) region of the brain contains high concentrations of mineralocorticoid receptors (MR) and glucocorticoid receptors (GR) that are important in the maintenance of body fluid and electrolyte balance as well as other physiological processes. Daily intracerebroventricular pulse injections of MR antisense oligonucleotides significantly suppressed deoxycorticosterone acetate (DOCA) induced salt appetite in a dose-related manner. Similar administration of GR antisense or scrambled/sense oligonucleotide into the third ventricle failed to inhibit salt appetite. Salt appetite aroused after adrenalectomy was not suppressed by MR antisense oligonucleotide treatments but was suppressed by an antisense oligonucleotide directed against the angiotensin II AT1 receptor subtype. Receptor binding analysis demonstrated that MR and GR oligonucleotide treatments each reduced their respective receptor subtypes. Finally, although GR antisense oligonucleotide treatment was ineffective in suppressing DOCA-induced salt appetite, this treatment did increase stress induced corticosterone release as well as delayed the recovery of corticosterone to basal levels after stress.
