Showing ONLY one Category doesn't work

Hi there,

I’ve been looking for solutions for hours now, but I couldn’t find anything regarding to my problem.
I have two categories I want to get shown separately: ‘News’ and ‘Jobs’.
In my loop-blog.php which is included in page-blog.php I want to get the category ‘News’ shown. This is what it looks like:

<div class="row news">
   		<?php
			$category = get_option('blog_exclude_categories');
			$category = explode(',', $category);
			if ($category) {
			  $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
			  $post_per_page = 6; // -1 shows all posts
			  $post_per_page = get_option('blog_items_per_page'); // -1 shows all posts
			  $do_not_show_stickies = 1; // 0 to show stickies
			  $args=array(
			    'category' => 1,
			    'category__not_in' => $category,
			    'orderby' => 'post_date',
			    'order' => 'DESC',
			    'paged' => $paged,
			    'posts_per_page' => $post_per_page,
			    'caller_get_posts' => $do_not_show_stickies,
			  );
			  $temp = $wp_query;  // assign orginal query to temp variable for later use
			  $wp_query = null;
			  $wp_query = new WP_Query($args);
			  if( have_posts() ) :
				while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
			    <?php endwhile; ?>

			    <?php $blog_related_posts = get_option('blog_related_posts'); // 0 = display, 1 = not display
					if($blog_related_posts == 0){ ?>
						<?php wp_reset_query();
						query_posts(array ('category=1', 'posts_per_page=4') );
						if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
						<div class="three columns">
							<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><h4><?php the_title(); ?></h4></a>
							<small><?php the_time('j. F Y'); ?></small>
						</div><!-- three columns -->
						<?php endwhile; else: _e("Leider ergab Ihre Suche keine Ergebnisse.", 'flowthemes'); endif; wp_reset_query(); ?>
				<?php } ?>			

			  <?php else : ?>
					<h2 class="center"><?php _e('Nicht gefunden', 'flowthemes'); ?></h2>
					<p class="center"><?php _e('Leider ergab Ihre Suche keine Ergebnisse.', 'flowthemes'); ?></p>
				<?php endif;
				$wp_query = $temp; //reset back to original query
			}  // if ($category)
			?>
   	</div><!-- row news -->
<?php /* Start loop */ ?>
<?php while (have_posts()) : the_post(); ?>
  <?php roots_post_before(); ?>
    <?php roots_post_inside_before(); ?>
    <div class="row start">
        	    <?php
				$args = array( 'cat' => 1, 'numberposts' => 2, 'order' => 'DESC', 'orderby' => 'post_date' );
				$postslist = get_posts( $args );
				foreach ($postslist as $post) :  setup_postdata($post); ?>
    	<div class="row single">
			<h2 class="sepa"><?php the_title(); ?></h2>
			<div class="row inner">
  				<div class="four columns">
					<?php the_content(); ?>
				</div><!-- four columns -->
				<div class="client-url">
					Link: <?php echo get_post_meta($post->ID, 'Link', true); ?>
				</div><!-- client-url -->
				<div class="eight columns thumb">
					<?php if (has_post_thumbnail()) {
  						the_post_thumbnail();
					} ?>
				</div><!-- eight columns -->
			</div><!-- row inner -->
    	</div><!-- row single -->
 		<?php endforeach; ?>
    </div><!-- row start -->
    <?php roots_post_inside_after(); ?>
  <?php roots_post_after(); ?>
<?php endwhile; /* End loop */ ?>

I told WordPress to show only the category with the ID 1. ‘Jobs’ has the category 14 and should be excluded from loop-blog.php

Neither $args=array('category' => 1,...)nor $args = array( 'cat' => 1,...) seem to be working. Don’t know what else I could try without getting a Parse Error.

Any ideas? Thank You!
